Chad looked at Carl's abandoned clothing, and down at his body. He picked up Carl's underwear and tossed it. Then put on Carl's discarded clothing. Carl had collected his wallet, keys and whatever other junk he had in his pockets, and had dumped Chad's stuff out on the floor of the field house. Taylor and Jake were struggling out of their harnesses. Jake had apparently gotten AJ's genes, and was now a butterball. Taylor and Chad had to undo his bonds. Chad was grateful for small blessings, at least he wasn't fat. He opened his wallet to check his ID, and balked. Whatever Carl and his buddies had done, apparently rewrote the jocks' histories. Chad's Driver's License now described his 4'9" tall male weighting 102 lbs. He examined his phone for photos, and balked. The one of him and Cindy Sue was replaced with one of the new him giving Carl a BJ. There was a comment with the photo. Keep drinking my sperm, Chad, and someday you may be a muscle stud too.
Chad grimaced. Just thinking about it put a sour taste in his mouth. He couldn't have? He didn't remember any of the crap that was now on his phone, and he didn't care how big Carl was now, he wouldn't stand for it.
He headed home to see what his family remembered. He didn't know what exactly Carl had done, but it must've involved time travel and gene manipulation from when they were conceived or born or not long after. Somehow Carl had stolen Chad's good jock genes and replaced them with his own nerd genes. It just didn't seem possible with human technology at its current level...damn, maybe Chad had gotten some good genes out of this - his brain seemed to be working faster, and thinking more complexly. He smiled, Carl might be in for a nasty surprise - if Chad had anything to say about it.
"Hi, Chad, how was school?" his mother asked.
"Uh, it was quite a day. Notice anything different about me?"
"Oh, you think you're getting a growth spurt? Here come over to the wall, I'll get the yardstick," she said excitedly.
She checked the pencil mark on the door frame against the top of Chad's head, and sighed, "Nope, still 4' 9", but if you feel like a growth spurt is starting. You should eat plenty of food and go to bed early."
"I got homework," Chad said with a sigh.
"You have got homework," his mother corrected.
Chad rolled his eyes, and started up to his room.
In the hallway, he ran into his big brother Brad.
"Hey, half-pint, think fast!" he said hurling his basketball at Chad. Chad caught it, but it was so fast and hard that he lost his balance and landed on his butt.
"Ooof! Ouch!" said Chad.
"Good work, Chad, this time you held on to the ball. Keep this up, and we'll make a jock of you yet," Brad said pulling the basketball out of Chad's hands, and heading downstairs and out of the house for a pickup game with his jock buds.
Chad lay on his back for a moment, and muttered, "Maybe it's only temporary? Maybe when I wake up tomorrow, I'll be normal?"
He entered his bedroom and froze. His girlie posters and sports fatheads were gone. Harry Potter and NASA posters covered the walls. He sighed. At least his trophy shelf was there, but the trophies were different. "Academic Decathalon," Spelling Bee, Math Whiz, Chess Championship, and the like - his sports trophies were gone.
He looked at the computer, and then he looked at the bed. He decided a little sleep would be helpful before he tackled the internet to try to figure out precisely what Carl had done and how to reverse it.
