"Alright" said Tom, "We could make this into a game. But remember, the machine said this was all permanent, so we need to be really care". "Yeah, of course man, only small changes, and nothing gross", Chris explained. "Exactly". "Well", Chris said, "I guess I am up first. Pick a change for me Tom; I'll close my eyes".
Chris closed his eyes as he could hear Tom typing on the keyboard. Tom hit enter and.... nothing? Chris felt the exact same. He stood there waiting for something to feel different until... OH GOD WHAT IS THAT SMELL?!
Chris's eyes darted open, and the first thing he saw was Tom trying not to burst out laughing. "What the hell is that smell?" Chris asked Tom. "Well, if the goal of this game was to hit puberty, than I just gave you one of the most obvious signs of puberty; B.O.!". Chris lifted one of his arms, sniffed it, and grimaced; he smelled absolutely awful, like a football linebacker after a half day long practice. "You asshole! This is permanent!" Chris yelled. "HAHAHA I know. And I gave you pretty bad body odor too! It's going to take a lot of deodorant and showers to even begin to cover that stench up!", Tom said in between bouts of laughter.
Chris smelled his armpits again; Ugggh they really reeked something fierce. And now he was stuck like this forever? He was disgusted. He had to get a fitting revenge on Tom.
