“Tell you what, kid,” you say. “It’s all well and good to face your fears, step up to your rival, and impress the girl. If you’re in a movie, that is. But this is real life, and in real life you’re going to get stomped unless you cheat. How about I arrange for that frat boy to have a little ‘accident?’”
“I don’t know… well, what kind of accident?”
And thus, just as it looks like the poor kid is going to lose the race, his opponent suddenly catches on fire, turns into a frog, gets scurvy, then trips and falls. Oops.
