Description[]
Back to the Future vs Disney/Pixar’s Up! Will Marty and Doc’s DeLorean be able to overpower Carl and Russell’s flying house, or will Carl and Russell send them “Up” to the afterlife?
Trivia[]
The connection between Marty and Doc & Carl and Russell is that they both consist of a duo of an elderly man and a younger boy. Both duos also own or encounter a dog but neither will be allowed in the fight. The elderly man was capable of building a contraption out of an ordinary thing (in this case, a car and a house) which allowed for flight and adventure. The elderly man also suffered from depression as Doc was depressed over never having a successful invention and Carl is devastated over his wife’s death. Both duos also appear in critically acclaimed movies often cited as some of the best in their respective fields.
Intro[]
Wiz: Older generations have increasing difficulty relating to their youth. Their old-fashioned values just don’t seem to mesh well with what their fellow kiddos like.
Boomstick: Unless said elders are capable of building these awesome contraptions.
Wiz: Marty and Doc, the time-traveling duo from Back to the Future.
Boomstick: And Carl and Russell, the high-flying adventurers who will make you bawl your eyes out. Starts crying
Wiz: Um, I’m Wiz and he’s Boomstick and it’s our job to analyze their weapons, armor, and skills to find out who would win… A Death Battle!
Marty and Doc go back in time for a DEATH BATTLE![]
Wiz: Marty McFly was just your average 80s teenager. He listened to rock music, hated school, and was constantly at odds with his parents.
Marty’s Background:
-Full Name: Martin Seamus “Marty” McFly (a.k.a Calvin Klein and Clint Eastwood)
-Age: 17
-Resident of Hill Valley
-Friends with Doc Brown
-Catchphrases include “This is heavy”, and “Nobody calls me chicken”
-Inadvertent creator of Johnny B. Goode
Popup: The director of Back to the Future has stated that the cartoon that takes place after the three movies is non-canon, meaning it won’t be factored into this debate.
Boomstick: Hey, I don’t blame him. What kid would be happy having an alcoholic mother and a dad who’s about as threatening as a fly. Honestly, we should apologize to all the combatants we’ve mocked over the years. Dan Hibiki, Starscream, Aquaman from the cartoon. Even Justin Bieber could kick George’s ass. Still, the guy did have some things going for him, such as being the leader of a rock band; the Pinheads to be exact. Seems the guy is a real horror aficionado.
Wiz: Uh, Boomstick, Hellraiser came out after Back to the Future.
Boomstick: Hey, at least I didn’t make an unfunny joke about my dad. Remember those days?
Wiz: Ugh, anyway, Marty’s guitar playing eventually led him at odds with a local bully, Needles. Jealous of Marty’s success, Needles wished to borrow his interocitor tube for his own band to use.
Boomstick: Interocitor what?
Wiz: It’s science stuff. Marty was willing to rent the tube to Needles for a small fee, but caused him to shatter it by grabbing his arm. Enraged, Needles threatened to beat up Marty if he couldn’t buy a replacement by 4:00, and it wasn’t soon after that he would first encounter the one and only Doc Brown.
Boomstick: Wait, what? That’s how they met? Some punk dropped a music tube and that’s how their friendship began?
Wiz: Well, it’s still better than how we met. You know, the time we—cuts to static.
Doc’s Background:
-Full Name: Dr. Emmett Lathrop “Doc” Brown
-Age:
1955: 65
1985: 95
-A scientist
-Names his dogs after scientists
-Favorite catchphrase: “Great Scott!”
-Can summon woman by singing
Boomstick: Anyway, Marty would find Doc’s garage in his search for that music thingie, but the attendant straight up warned him that the Doctor was a “real nut case”.
Wiz: And you know what? She was right. I mean the first thing Doc did was set up traps that Marty had to overcome just to enter his lab. He even had a keypad that gives off an electric shock when the incorrect password is put in and straight up captured Marty in a net with a series of well placed objects.
Boomstick: That kinda like how I get my beer.
Wiz: Still, Marty was able to escape the net and an impressed Doc Brown offered him up as his assistant.
Boomstick: Alright, Wiz. Can we get to the good stuff? You know, the stuff about the time travel and the DeLorean and the making out with his mom?
Wiz: That’s right where we’re heading. Marty and Doc would continue to bond for the next three years.
Boomstick: Geez, Marty must have some really low standards given his friend is a sad, elderly man who lives alone in his lab and spends every day building things like a barbed alarm clock, or a wearable tissue dispenser.
Wiz: But everything would change when Doc would unveil his newest invention: A time machine!!--out of a DeLorean. Powered by Doc’s, ahem, flux capacitor, it apparently has the power to travel anywhere in time by reaching speeds of 88 mph.
Boomstick: And knowing full well that this experiment was dead on arrival, Doc Brown held his friend for the final time as the Delorean would inevitably run them ov-Wait! Hold on! It worked?
Wiz: Indeed. Doc’s attempt at scientific advancement had finally paid off. Too bad he was quickly shot down by Libyan terrorists over a nuclear bomb deal gone wrong. With nowhere else to go, Marty stepped foot in the DeLorean but accidentally accelerated to 88 and due to the date Doc had typed in moments earlier, Marty discovered, much to his horror, that he was in 1955.
Boomstick: Ah, the 1950s. The time of Pez candies and poodle skirts. What’s so bad about that?
Wiz: Boomstick, how do you know so much about the 50s when you weren’t even born back then?
Boomstick: Well, I may have stolen a little something from a certain Justice League member. Hal Jordan’s Lantern Ring! With this device, I can travel to any point in time I wish. I know, I’ll travel to the start of this analysis to prevent our viewers from hearing that boring backstory!
Wiz: Boomstick no-Boomstick taps the ring and travels to the start of the analysis.
Past Wiz: Marty was willing to rent the tube to Needles for a small fee, but caused him to shatter it by-Future Boomstick appears and lands on Past Wiz, causing him to fall to the ground and groan in pain.
Past Boomstick: Hold on, am I seeing double?
Future Boomstick: Don’t ask. Anyway, with his car out of fuel, Marty had only one option: To talk to the scientist he just saw get murdered in front of his eyes and ask him for help. Geez, you’d think the guy would’ve had trauma from that experience.
Past Boomstick: Luckily, Marty quickly convinced Doc he was of a different time, and the younger but still dateless doctor had but one goal: to get Marty back to the future!
Arsenal and Skills:
Marty McFly:
-Skateboard
-Hoverboard
-Guitar-playing
Doc Brown:
-DeLorean
-Time-traveling steam engine
-Knockout gas
Future Boomstick: And the two certainly had the skills necessary to succeed. Despite being a teen, Marty is quite strong for his age. He can trade blows with much bigger guys like Biff and his great grandfather Mad Dog Tannen.
Past Boomstick: Marty is also an expert at skateboarding. The guy was able to outpace a speeding car for a short time while on his board. And if that isn’t enough to impress you, the guy also wields a hoverboard which allows Marty to skate while airborne and cross wide terrain.
Future Boomstick: It’s unclear if the hoverboard is capable of flight as it has shown to gain height in certain situations, but either way, it is an exceptional device for getting out of tight corners.
Past Boomstick: And as lame as Doc Brown might seem at first, the guy has a real knack for getting Marty out of tight situations. Like the time Michael, sorry, Marty was being hung by a noose and Doc was able to get him down with a single shot from a gun.
Future Boomstick: Man, I wish I had a dad like that.
Past Boomstick: Hey! I thought I told you, or I guess me not to make any more dad jokes. Hey me! Don’t make anymore dad jokes!
Future Boomstick: Wait, since you swore off from doing what I will do in the future, does this mean…aaahhhhh! Vanishes from time
Wiz: Wakes up. Hold on, where am I?
Boomstick: You fell asleep in your car. Speaking of which, Marty and Doc’s greatest tool for combat is unquestionably their DeLorean. This bad boy can not only fly, but it can reach 88 mph in only a few seconds. If Marty and Doc are on death’s door, nothing’s really stopping them from using the DeLorean and messing with time. Plus, they can just ram into their opponents and mess ‘em up that way.
Wiz: Well, it’s unlikely they’d resort to such a tactic, as Marty and especially Doc aren’t much in the way of fighters, preferring instead to outsmart their opponents, though they certainly aren’t afraid to use brute force if they have to.
Feats:
-Defeated Biff Tannen and Mad Dog Tannen
-Survived an electric shock from lightning
-Built a time-travel machine out of an 1800s steam engine
-Had a ravine named after him
-Survived advancements from his mom
-Helped George grow a spine
-Saved the world from a nuclear holocaust
-Can play the guitar just like he’s ringing a bell
Boomstick: Marty and Doc have been through some pretty intense stuff, such as an alternate dystopian future, and have stood up to three Biffs as well as his great-grandfather from different time periods.
Wiz: But while they may have been able to save their timelines, they have also led to them changing for the worse, such as when Marty foolishly left a sports almanac out in the open while an elderly Biff was just around the corner, allowing him to steal the DeLorean and alter the past in his favor. Also, while the DeLorean is an extremely powerful device, it’s also just as fragile as a regular car and was easily destroyed upon being run over by a train.
Boomstick: Plus, Marty has some serious self-esteem issues. LIke geez, the guy has put himself in so many bad positions because he just can’t handle getting called a chicken. In fact, that’s the whole reason Needles got him to look for the interocitor thingamajig.
Wiz: Oh, that reminds me. We forgot to tell the audience about how Marty and Doc met.
Boomstick: Nooooo! Punches Wiz.
Wiz: Ow! Falls to the floor.
Boomstick: Still, if you find yourself in the headlights of these two time-travelers, you’re gonna wish you were the one who was never born.
Carl and Russell adventure into DEATH BATTLE![]
Wiz: Let us travel even further back in history, all the way to the 1930s; A more adventurous time. It was here that the world would be introduced to many great explorers who traveled the land, the most famous of whom was Charles F. Muntz. Described as a beacon of hope for the American public, Muntz was also an inspiration for those willing to travel the world and follow his signature mantra:
Boomstick: “Adventure is out there!” Sorry, had to say the line.
Wiz: But no one idolized Muntz quite like Carl Frederickson.
Carl’s Background:
-Full Name: Carl Frederickson
-Age:
9 (1939)
78 (2009)
-Possibly of Norwegian descent
-Has a square-shaped head
-Inspired by the old man from The Giving Tree
-Really misses his wife
Boomstick: Yeah, young Carl adored the public figure and made it his goal to travel to Paradise Falls one day.
Wiz: This became even more important to him when he met a girl named Ellie who shared his love for adventure.
Boomstick: The two were instantly meant for each other to the point where they never left each other’s side since youth. Wow, I’m not sure if I should be happy for them or concerned. I know love conquers all or whatever but being with the same guy for your entire life must really get old after a while. That’s the whole reason I broke up with my ex-wife.
Wiz: Uh, Boomstick, I thought she dumped you after you drove your truck through her house.
Boomstick: Oh, you're right! That’s when I discovered my real true love: beer! Pulls out a beer and hugs it before drinking from it and burping.
Wiz: Uh, anyway, things were going great for the two lovebirds, until Ellie tragically died of old age.
Boomstick: Yeah, yeah, I know it’s one of the saddest deaths ever but it’s still not as sad as when McGruff died on this show. Starts crying. I’ll remember you McGruff, always…
Wiz: Carl was devastated to the point where he would become increasingly bitter and isolated from the world. Things would get even worse when Carl was sentenced to a retirement home after assaulting a worker and labeled a public menace. It seems Carl’s dreams of traveling the world were over.
Boomstick: That is, until the guy decided to tie every balloon he had to his house and fly away. Geez, Carl must’ve gone crazy or something. I mean, there’s no way-holy shit! How!
Wiz: That’s right, Carl’s brief tenure as a balloon salesman paid off as tying hundreds of balloons to his house somehow resulted in it gaining flight. Carl was free and finally had the chance to reach the place of he and his wife’s dreams: Paradise Falls.
Boomstick: Unfortunately, Carl’s journey wasn’t going to be easy as the falls were full of dangers that would cause your average old man to die of dementia.
Wiz: Luckily, Carl had all the tools he needed to combat the tropical troubles.
Arsenal:
-Cane
-Tennis Balls
-Balloons
-Flying house
-Dentures
-Hearing aids
-Leaf blower
-Russell
Boomstick: His main weapon is his cane which he can use as a melee weapon and smack his enemies away. He can further aid himself with tennis balls attached to the bottom which he can take off and throw as a projectile. Also, you know how Mike Tyson likes to spit on his opponents in boxing? While Carl does that too, only he spits out his dentures, sacrificing his dental care in favor of a sweet surprise attack.
Wiz: Now, you might think that spitting out dentures would hardly be an effective attack, but amazingly, Carl can spit hard enough to daze an adult like Charles Muntz, who by the way, is actually a psychopath willing to murder children.
Boomstick: You know, I just realized, Wiz. Russell is one of the combatants for this fight, but we haven’t said anything about him yet.
Wiz: Um, yeah.
Russell’s Background:
-Full Name: Russell (a.k.a The Small Mailman)
-Age: 8
-A wilderness explorer
-Design based of a young Peter Sohn
-Hates his father’s girlfriend Phyllis
-Favorite Song: Surfin’ Bird
-Has no powers or abilities
-Likes chocolate
Wiz: Russell is this 8 year old kid who likes exploring. His parents divorced and he probably got his ass kicked at school. Still, he’s somehow collected enough badges to become a senior wilderness explorer and doesn’t mind that his dad cares so little for him, he didn’t even notice that his son disappeared for days on end.
Future Boomstick’s Voice: Kinda like my dad! Hahahahahaha!
Boomstick: Arrrrrrrrgh!
Wiz: Plus, the guy can communicate with birds like Kevin and summon him with chocolate.
Boomstick: Actually Wiz, Kevin’s a girl.
Wiz: Unlike your beer. Hahahaha-
Boomstick: Punches Wiz to the ground. Anyway, Russell is also surprisingly strong, as he was capable of holding on to the bottom of Carl’s house as it was flying away and somehow climbed onto the front porch. That’s the kind of stuff even Olympic medalists would struggle with. Still, when it comes to physicality, Carl is the main man.
Feats:
-Lifted a several ton house into the air with balloons
-Tied hundreds of balloons in less than a night
-Defeated Charles Muntz
-Endured a 50+ year marriage
-Climbed onto the front porch of Carl’s house while it was airborne
-Helped Kevin find her chicks
-Graduated to Senior Wilderness Explorer
-Made millions of grown adults cry over a kids movie
Boomstick: Not only can he somehow endure pulling his house behind him for days on end, but he’s also strong enough to temporarily stop it from falling off the side of a zeppelin. Remember when those things were popular?
Wiz: Plus, the guy somehow tied hundreds of balloons to the top of his house in less than a night and his balloons were somehow strong enough to not only lift his house into the air, but also rip it from the utility pipes holding it down. Compared to Carl’s size, his house appears to be really big. In order for his balloons to rip the house off the ground and lift it into the air, they must be capable of lifting many tons of weight. Plus, assuming an estimate of around 200 balloons, each balloon must be strong enough to hold a very large amount of weight as well.
Boomstick: As impressive as Carl and his flying house are, though, he’s still just a human and his old-age does hold him back from being a capable fighter. Plus, as strong as his balloons are, they are just as easily popped as an ordinary balloon.
Wiz: And don’t even get us started on Russell. Not only does he possess no combat experience whatsoever, but he’s more likely to get kidnapped than help. Honestly, Carl should be thankful Ellie had that miscarriage.
Boomstick: Still, any aspiring explorers should hope to get on Carl and Russell’s good side as unless you’re Schaffrillas Productions, you’re gonna have a difficult time making them look bad. Also, that reminds me. Why the hell does that Megamind video by crab boy have more views than over a third of our content? YouTube’s algorithm is weird.
Interlude[]
Wiz: Alright, the combatants are set and we’ve run the data through all possibilities.
Boomstick: It’s time for a Death Battle!
Fight[]
The battle opens with Carl, Russell, and Dug the dog sitting on the front steps of Carl’s house, playing Russell’s favorite game where they name the colors of passing cars.
Russell: Red one!
Carl: Blue one!
Dug: Gray one!
Carl: Haha, this is so much fun! I feel like a kid again!
Russell: Yeah, this game is the best! I wish I could play it for the rest of my life.
Dug: Woof woof squirrel! Dug sees a squirrel and runs across the road in pursuit of it.
Carl: Woah! Be careful, Dug.
Suddenly, the DeLorean appears through time and it ends up running over Dug, killing him and leaving his body bloodied and broken.
Russell: Dug!
Carl: Oh no!
Carl and Russell run over to the dead dog with Russell crying over his fallen friend.
Russell: Dug, wake up, please!
Enraged, Carl runs over to the DeLorean as Marty and Doc are getting out.
Carl: You monsters! Why don’t you watch where you’re going?!
Marty: What are they talking about, Doc?
Marty looks over and sees the dog they ran over.
Marty: Oh.
Doc: We’re deeply sorry, sir, but there was no way for us to know your dog would run across the street at this point in time. Maybe you should talk to your wife. I’m sure she’d understand.
Reminded of his wife’s tragic passing, Carl becomes even more angry to the point where he lifts up his cane and whacks Doc in the head.
Doc: Ow! What the..
Carl strikes Doc with his cane a few more times and ends his attack by kicking him to the side. Marty is shocked by Carl’s sudden act of violence and rushes to Doc’s aid.
Marty: Doc! Are you okay?
Doc: Get outta here, Marty. I’ll handle this myself.
Marty runs off and decides to attack Russell.
Doc: So you wanna fight, old man? Just be warned that you’re messing with the smartest man in the world.
Carl attempts to hit Doc with his cane again, but this time Doc grabs it with his hands before kicking Carl in the groin.
Carl: Moans in pain
Doc follows his kick with several punches on Carl’s face, with the last one knocking the dentures out of Carl’s mouth.
Carl: (Talking with only his gums) So you like to play with balls, ay? Well, I’ve got plenty!
Carl throws the tennis balls on his cane at Doc who is caught off guard by the sudden attack. Meanwhile, Russell is still mourning Dug until Marty runs over and pushes him to the ground.
Russell: Ow! What was that for?
Marty doesn’t respond and continues attacking Russell by throwing a rock at his face and kicking his body continuously. Doc, meanwhile, is out-ranged by Carl swinging his cane side-to-side. Luckily, Doc could tell Carl has hearing aids, so he yells so loud, Carl’s hearing aids go off which distracts him and allows Doc to grab his cane and push it in Carl’s direction which knocks Carl to the ground and allows Doc to grab it for himself. Carl, still dazed from the attack, opens his eyes and sees Doc standing tall over his body and preparing to strike Carl with his own cane. As for Russell, he is still getting whooped by Marty until he remembers he has chocolate in his pocket. He takes it out and yells “chocolate!”. Somehow, despite Kevin being all the way back at Paradise Falls, he hears Russell’s cry and the big bird arrives almost instantly.
Russell: Kevin!
Marty: What the hell?
Before Marty can react, Kevin rams into Marty so hard, he gets launched across the street all the way through the back window of the DeLorean.
Russell: Yeah! Get ‘em Kevin!
Kevin uses his beak to help Russell up and lifts him onto his back before walking towards Doc Brown. Just as Doc is about to strike Carl, he sees the giant bird in his view.
Doc: Great Scott!
Doc started running away in fear but the bird was far too fast for him. Kevin leaped high into the air and landed feet-first on the poor scientist, breaking nearly all his bones instantly. The Doc was in great pain but still alive. Suddenly, Carl walked over with plans for Mr. Brown.
Carl: Alright mister. You’ve murdered my dog and let your crazy grandson attack an 8-year-old. Now you’re gonna pay. Cover your eyes, Russell.
Doc: Please, sir, I’ll do anything.
But Doc’s words were quickly silenced as Carl started bashing his brains in with his cane, his blood splattering all over the place. Doc’s face was barely recognizable with blood pouring out of his head and his skull being partially visible. It was certain: the scientist was dead. Knowing what might happen if the police saw what he just did, Carl’s only option was to escape with his balloon house, much like how he escaped the authorities before.
Carl: Russell, Kevin, we need to get out of here.
The three walked into his house, with Carl leaving blood stains on the front steps. Carl quickly released his balloons which caused his house to fly into the air, leaving the time-traveling duo behind them. It seemed their troubles were over… until the fight cuts back to the DeLorean which reveals that Marty is in the backseat and still alive. Though gravely injured from being launched by Kevin, he manages to climb into the front seat and activate the car once more.
Marty: Argh, you bastards may have killed Doc, but don’t think you’ll escape from me.
Instead of traveling back in time, Marty uses the DeLorean to fly up to the airborne house. As Marty reaches it, he opens the door on his side, but instead of going inside the house, Marty takes out his guitar which he happened to bring with him.
Marty: Hey, bastards! You ready to rock-and-roll?
The high frequency of the guitar-playing causes the balloons lifting the house to start popping. Carl and the others quickly realize this.
Russell: Mr. Frederickson! The balloons are popping!
Carl: I know Russell. Stay calm, let me see what’s causing it.
Carl looks out the front window and sees Marty playing his guitar.
Carl: Argh, I thought he was dead. Kevin! Russell! Come over here.
Carl opens the front door with plans to jump on the DeLorean before the house falls.
Carl: Hey, kid. Knock it off or we’ll steal your ride!
Marty: Oh, yeah? Continues playing
Carl: Ugh, Kevin, come toss me on there.
Kevin grabs Carl with his beak and tosses him on the hood of the DeLorean, startling Marty with the noise his landing makes.
Carl: Alright, Kevin! Your turn!
Kevin was about to jump off the porch but unfortunately, the last balloon holding up the house popped, causing the house to suddenly fall from the sky and crash upon hitting the ground, killing both Russell and Kevin.
Carl: Russell! Kevin! Nooooo!
Marty: Hopefully you got some insurance. Hahahahaha.
Enraged once more, Carl grabbed his cane which he still had with him and smashed through the front window of the DeLorean. He jumped at Marty and started choking him with his bare hands. Not wanting to lose to an old man, Marty grabbed a glass shard from the front window and stabbed Mr. Frederickson in his right eye. While he was crying out in pain, Marty used his left arm to push the DeLorean’s gas pedal causing Carl to fall backwards. As the car was speeding through the air, Carl used the handle of his cane to impale Marty through his left leg. He then took after Marty and used a glass shard of his own to stab Marty in his chest, barely missing his heart. Despite the insane amount of pain he was in, Marty was still pushing tightly on the pedal and the MPH counter would continue to rise. 79, 80, 81, 82. Seeing Marty’s willpower on display, Carl, who still had the glass shard in Marty’s chest slowly sliced upwards towards his heart, expecting to cut into it and kill him. Things seemed hopeless for Marty, until his cunning plan came into action. Before flying up to Carl’s house, he had input a destination time into the DeLorean that would take him and Carl to just before the Big Bang happened. Just before the car reached 88 mph and before the glass shard reached his heart, Marty jumped out of the DeLorean through the open door behind him (he had previously opened it before playing his guitar). The DeLorean travels through time with just Carl in it who arrives in a seemingly empty void.
Carl: Jiminy Cricket, where am I?
A second later, the Big Bang happens, instantly vaporizing a screaming Carl along with the DeLorean. Back in the present, Marty is falling from the sky, but he secretly had his hoverboard tied to his back. After ripping it off, he rides it to the ground below. A victorious Marty jumps off before saying one final line.
Marty: Whoa, that was heavy. Welp, might as well go bang my mom. He runs off.
KO!
Conclusion[]
Boomstick: I wonder if Ellie wishes her death was as awesome as getting killed by the f**king Big Bang.
Wiz: This was certainly an interesting match to pick apart. Both teams have shown next to no superhuman capabilities making this battle more dependent on their inventions.
Boomstick: As impressive as Carl’s flying house is, it doesn’t have much use when it comes to combat. Not only is it far too slow to be a useful means of traversing the battlefield, but once enough of those balloons get popped, it’s game over.
Wiz: Doc and Marty’s DeLorean, meanwhile, while also not designed for combat, would prove to be a far more effective weapon. Its rocket-powered flight gives it more control over the air then Carl’s balloons and its ability to reach speeds of 88 mph in only a few seconds is far faster than anything the two adventurers could handle.
Boomstick: Plus, there was really nothing stopping Marty and Doc from just traveling back in time to give themselves the advantage. They could go back to the start of the fight whenever they wanted and kill Carl and Russell by dive bombing into them.
Wiz: Granted, Marty and Doc aren’t exactly known for resorting to such cheap tactics and it’s highly unlikely they would ever resort to killing in the heat of battle. However, the same could be said for Carl and Russell who have next to no combat experience outside of dealing with Charles Muntz and have very little options that could put the time-travelers down. A guy with a cane can’t do much against a guy with a flying car.
Boomstick: Carl and Russell were certainly skilled enough to reach Paradise Falls but taking out a pair with time-travel on their side is a different story. I guess you could say they had nowhere to go but down.
Wiz: The winners are Marty and Doc.
