You churn it over in your mind a second... "So.. If I bet the years, I lose them even if I get the answer right?". You think a couple more seconds "That doesn't sound right.". The Barker thinks it over a bit. "Oh, sorry kid! This is my first day, I messed up on the rules. You're right.". You smile. "So... are you going to change me back?". He looks at you in a somewhat embarrassed manner. "I would, but you need to get another answer right for the magic to activate. If you're having trouble thinking, just wait a second or two more, you should still have all your knowledge from when you were 18.". You do as he says, and in a few more minutes, you're thinking clear again. It's as though a fog was lifted from you.
"I'll play again... the same category, and I'll bet... um." You say, thinking you don't want to make yourself too young if you get this wrong. You want to be able to talk to get your answer out. 3 years should do. "And I bet 3 years.". The Barker looks at his card. "Uma Thurman, who played the Bride in last years 'Kill Bill', was also a main character in what other Quentin Tarantino movie?". You smile, thinking how easy this question is. "She was in pulp fiction.". The Barker shouts out "Correct!". In an instant, you feel warm. You look down to see yourself growing taller again. In a few seconds, it stops. You're much taller now, you check everything out. "Want to go again, Kid?" He says. "Sure. 6 years now." You say, knowing you don't want to go under 5 years old.
"Allright, Keanu Reeves starred in what 1990's horror movie?". Another easy one! "He was in Brahm Stoker's Dracula!". Again, the bell dinged. You felt really warm now. You started growing taller once again. Pulling open your pants, you see that you 11 year old dick was growing, and a patch of hair was forming around it. 13 years old... 14, 15. It was back to it's old length! You were a few inches short of your original height though, and as you bulked up at 16, you grew to your full 5'10". You were 17 years old again... now, all you needed was one more year... but what would it be like to be even older? The thought crawled into your mind. How about 22? Surely with such easy questions, you should be able to get another 5 years. "5 year bet, same subject please.". "Okay kiddo... what year was the movie 'Jacob's ladder' made in?".
Your heart drops... you don't know this one. "Umm... 1980?". "Wrong, kiddo. Sorry about that! That's 5 years off.". You feel yourself getting shorter again. 16 years old, 15 years old... you're losing those muscles and that height you'd just won. You pull open the pants to see your pubic hair receding, and your dick is shrinking again. When you hit 13, your whole body size drops considerably, and at 12 you're back at pre-puberty. "I want to try again!" You shout in your uncracked voice. "Sorry kid, I'm shutting down for the night. There's other stuff round here for you to do, go find something else until tomorrow."
