Brad rode along in Jim's car, feeling his muscles slowly growing, and noticing how buff Jim looked as well.
"Damn," Jim said after a few minutes. "I can't get over being this buff. It feels like my clothes keep getting tighter. In fact, I think they are..."
Jim pulled the car over and flexed a bicep. It was incredibly huge and defined, stretching the sleeve of the shirt taught. "What's happening?"
"Uh..." Brad said. "It looks like your muscles are growing." He glanced at Jim, and noticed he was glancing up. "And I think you're getting taller too."
"Huh?"
Brad pulled open the laptop and checked the stats on the screen. Indeed, Jim's muscles had grown, and he likewise had grown taller. He now was listed at 6'3" in the program.
"Damn," that's bigger than I was? What's happening? Can you stop it?"
Brad tried to, but had a screen popup that said WARNING: PROGRAM EXECUTING. DO NOT ABORT. 53 MINUTES REMAINING.
He looked at the screens. He was growing, by the program he'd put it in, but it appeared that Jim had become listed under his own "clothing and accessories."
"What's happening?" Jim demanded.
"Uh," Brad said, "it looks like when I grow, my clothing grows with me, so it's making you bigger as it makes them bigger to accommodate my muscles." He looked at a few more screens. "Oh my god..."
"What?" Jim demanded.
"The muscles. It's not increasing yours by the same number of pounds as mine, but in relation to the proportional increase of mine relative to fat percentage. But you have less than 1 percent body fat as it is. It's increasing your muscle mass so that your relative fat percentage decreases in the same proportion as mine."
"I'm turning into the Hulk?"
"Except not green, but yeah."
They watched as Jim increased in size and proportional muscle mass, and finally, at the end of the hour, he was 10'9" and 1027 lbs of immense muscle.
PROGRAM COMPLETED the Chronivac displayed.
"Can you fix me?" Jim pleaded.
Brad decided to just go to command lines and typed in: Return Jim to previous dimensions immediately.
The Chronivac replied: Immediate transformations require trigger. Please specify trigger.
Brad didn't know what it was talking about exactly, but guessed. "I think it wants a password. Have a favorite?"
"Pizza," Jim said immediately. "Please, fix me."
Brad typed in "PIZZA" and hit Enter.
ACCEPTABLE TRIGGER. APPLYING METABOLIC CHANGES.
There was a sparkle on the screen, then a sudden inrush of air as the giant bodybuilder transformed back into a somewhat out of shape seventeen-year-old pizza deliver boy.
Then there was another sparkle, and just as suddenly Jim transformed back into the non-green teen Hulk.
"What happened?" he demanded.
Brad looked at the screen, typing for readouts on Jim, then finally reported. "It says that there's still some pizza in your digestive tract and it will be another eleven hours before your body can fully process it, give or take."
"What?" Jim gasped.
"It looks like you'll turn into the hulk whenever you eat pizza. Sort of a Popeye effect." He looked on the readouts. "On the plus side, it looks like all the pizza you eat will be processed into permanent body mass, so if you want to bulk up to somewhere in between, you just need to chow down and be the hulk for a while."
