Mordecai and Rigby give Muscle Man a fake winning lottery ticket to get back at him for always pranking them. But a warning from Skips about how seriously Muscle Man takes getting pranked when money is involved makes them scared to confess the truth to Muscle Man. Things start to get out of hand when Muscle Man starts breaking things around the park, under the belief that he can pay to replace them.

----
!! Tropes
* AcquiredSituationalNarcissism: Once Muscle Man thinks he's going to win a million dollars, before he even has it, he insults his friends and starts trashing the entire park because he figures he can just replace everything with something new. This happens despite two episodes earlier Muscle Man not reacting the same when landing a dream job, instead valuing friendships more.
* BaitAndSwitch: Earlier in the episode Mordecai and Rigby imagine Muscle Man shoving them into a vending machine and throwing it into the distance to get back at pranking him with the fake ticket. When they actually tell him the ticket's fake, he appears to do exactly that except he shoves them in a lottery ticket redemption machine instead. [[DaydreamSurprise Except they imagined]] ''[[DaydreamSurprise that]]'', [[DaydreamSurprise too]].
* BigEater: Muscle Man stuffs himself with ''dozens'' of chicken wings at Wing Kingdom.
* CallBack: The opening shots from the fridge as both Muscle Man and Mordecai reach inside mimics the opening of the show's original pilot.
* DidntThinkThisThrough: Mordecai and Rigby prank Muscle Man into thinking he won $1 million, not taking into account ahead of time how he would actually react to it.
* DisproportionateRetribution: Muscle Man shoves Mordecai and Rigby into the lottery ticket redemption machine and throws it into the distance where it explodes. Except not really, the duo imagined it. But after they actually confess that the ticket is fake, it's implied that Muscle Man plans to inflict bodily harm on the two later.
* EasilyForgiven: Muscle Man is let off the hook for damage he caused since the fake tickets have been in recall for months, and not only do they apologize, all damage to lottery property (the park's damages on the other hand is not their problem according to "the contract") will be covered. Muscle Man also forgives Mordecai and Rigby for their prank, complementing them on it, but still states they'll need health insurance for when he pranks them back.
* ExactWords: Muscle Man, during the ImagineSpot where the duo confess their prank.
-->'''Muscle Man:''' It's okay. I'm not mad.\\
'''Rigby:''' Really?\\
'''Muscle Man:''' Nope. '''''[[SuddenlyShouting I'M FURIOUS!!!!]]''''' ''(shoves Mordecai and Rigby into the lottery machine and tosses it out, in which it explodes)''
* EvilLaugh: Muscle Man lets out one at the end of the episode as he states that he'll eventually get back at Mordecai and Rigby for pranking him.
* GoneHorriblyRight: Mordecai and Rigby prank Muscle Man with a fake lottery ticket and he believes he is now rich. But their plan to immediately tell him it is a prank fails when they learn of the danger, and Muscle Man starts breaking things under the belief that he can afford to replace them.
* GracefulLoser: When Mordecai and Rigby finally confess to Muscle Man that they pranked him, he's actually very cool about it and admits they got him good. Although in the end he tells them he's gonna prank them back big time.
* ImagineSpot: Mordecai and Rigby imagine that if they tell Muscle Man that the lottery ticket is a fake, he'll shove them into a vending machine and throw it into the distance where it explodes. Then when they actually tell him it's a fake, he does exactly what they were afraid he would do, except with a lottery ticket machine instead. Except that was ''[[DaydreamSurprise also]]'' an imagine spot.
* ImpliedDeathThreat: After Muscle Man admits that Mordecai and Rigby got him with their prank, he asks if they have health insurance. Because they'll need full coverage when he pranks them back.
* ItsPersonal: Skips explains that the last time someone pranked Muscle Man when money was involved was at the park raffle a few years ago, when a man named Biggs had called out Muscle Man's ticket number as the winning one, but then changed it by saying it was the one directly below his number, pranking him. Muscle Man didn't take it very well and did something to him.
* JabbaTableManners: Muscle Man munches on all the chicken wings like there's no tomorrow, grossing both Mordecai and Rigby out.
-->'''Muscle Man:''' Are you sure you guys don't want anything?\\
'''Mordecai:''' Uh, no thanks. Water's good.
* NoodleIncident: Skips explains that the last time someone pranked Muscle Man when money was involved, Muscle Man didn't take it very well and did something to him. Skips forgets if he never "walked" or "worked" again though because he never liked the guy.
* UnstoppableRage: When Muscle Man tries to cash in his fake lottery ticket and it is rejected he goes crazy and goes on a rampage. Armed S.W.A.T-like lottery employees try to stop him but are [[CurbStompBattle easily overpowered]]. Muscle Man only calms down when he is finally told that the ticket is a fake and he was pranked.
* VerbThis:
-->'''SWAT member:''' Sir, disrupting and tampering with lottery machine is a federal offense. If you do not stop, we ''will'' use force.\\
'''Muscle Man:''' [[PreAsskickingOneLiner Force this!]] ''(throws the guy to the wall)''
* WhatTheHellHero: Rigby says out loud to Muscle Man that Mordecai has something he wants to tell Muscle Man (the lottery ticket being fake). Mordecai chickens out and tells Muscle Man something completely different, and Rigby's reaction towards Mordecai is this trope.
