Big Winner

Muscle Man continuously pranks the trio. He shakes a bottle of soda which Mordecai opens and it spills on him, (Y/n) and Rigby. Muscle Man laughs. "Gotcha dudes!" (Y/n), Mordcai and Rigby head through a door and a bucket of water lands on them. "Gotcha dudes!" (Y/n), Mordecai and Rigby are now playing a video game but their thumbs are stuck on a controller due to glue. Muscle Man is then seen again holding a tube of "Gloop D' Glue" "Gotcha dudes!" The trio are then at the hospital with (Y/n)'s, Mordecai and Rigby's thumbs still stuck onto the controllers. "Gotcha dudes! Gotcha dudes! Gotcha dudes! Gotcha dudes!" Muscle Man said.

The trio are now at the park where they are celebrating Muscle Man's birthday. "Happy birthday Muscle Man!" Everyone said. "Alright, gifts!" Muscle Man said as he tears off wrapping paper. "Dudes, it's time to put Muscle Man in his place. You got the fake lottery ticket?" (Y/n) asked. Rigby holds up an envelope. "Hm, hm, hm, hm, hm, hm!" The trio walk towards Muscle Man. "Hey, Muscle Man, happy birthday." Mordecai said. "Here's your birthday gift from us." Rigby said. Muscle Man tears open the envelope. "What's this? Aw, a lottery ticket?

Wow, you losers really bent over backwards to get me a great gift." He said. "Come on, just scratch it." (Y/n) said. "Yeah, right, I'm not scratching nothing. Nobody wins these things." Muscle Man said. "Come on, scratch it dude. You could win a million dollars." Mordecai said. "Fine, but I'm keeping this quarter." He grumbles and scratches a one million. "One one million, big deal." He grumbles and scratches a second one million. "Whoa, two in a row! Okay."

He murmurs and scratches a third one million. "I matched all three! I won, I won! Kiss my rich butt, losers. Woo!" He runs and spins around on grass, and the trio laugh evilly. "Dudes, he totally fell for it." (Y/n) said. "I can't wait to see the look on his face when we tell him we pranked him! Come on." Rigby said. "Wait, guys. You gave Muscle Man a fake lottery ticket?" Skips asked. "Yeah, why? What's the big deal?" Mordecai asked. "The last guy who pranked him with money didn't end up so well. It all happened a couple of years ago during the park raffle." Skips said.

"And the winner of the one hundred dollar gift prize is ticket number three four six." Biggs said. "Woohoo! It's me! I won a hundred bucks, baby!" Muscle Man shouted. "Oops! That's not the right ticket number." Biggs said. "Huh?" Muscle Man asked. "The real winning number is three four five!" He laughs. "Gotcha, Muscle Man!" He laughs again. "Look at your face!" He said. Later Biggs is walking out of a small building. "Muscle Man didn't find the prank as funny as Biggs did." Biggs uses a vending machine until he sees Muscle Man's reflection and turns around. "That was a pretty good prank you pulled back there, bro. I should return the favor. One good prank deserves another." Muscle Man cracks his knuckles and Biggs gasps.

"What happened to the guy?" (Y/n) asked. "He never walked again. Or worked again, I can't remember, I don't know, I didn't really like the guy. But I like you guys, which is why you should be careful about telling Muscle Man you pranked him." Skips said. "Dudes, he almost killed a guy over a hundred bucks, imagine what he'll do to us over a million dollars!" Mordecai shouted. The trio imagine that Muscle Man shoves them into the same vending machine and throws the vending machine. "Okay, don't panic, we just gotta go tell him before it's too late, come on." (Y/n) said.

The trio walk up to Muscle Man, who is wrecking a table. "Hey, Muscle Man, we need to tell you something." (Y/n) said. "Hold up, bros, I'm busy." He elbows the table. "Whoa, whoa, Muscle Man, what are you doing?" Mordecai asked. "Now that I'm a millionaire, I'm gonna do some serious remodeling to this place. Now don't interrupt me again or I'll remodel your face." Muscle Man smashes the table with his head. "So maybe now's not a good time to tell him?" Rigby asked. "Yeah, probably not a good time." Mordecai said. "I'll put the Jacuzzi here." Muscle Man smashes the sofa. "And the flat screen here." He smashes the television.
