Tragicomedy

My brother told me this joke when we were little. I liked the joke so much, I can still remember how my brother acted out the scene. Read on:

A man was walking by an alley when he saw a kid jumping over a makeshift trampoline. Curious, he walked up to the kid.

Man: Hey kid, that looks dangerous, what are you doing?

Kid: 65! 65! 65! 65! Bet you can't do this!! *grins* 65! 65! 65! 65!

Man: What do you mean 65, hey.. stop that you might hurt yourself..

Kid: Hahah! 65! 65! 65! 65! Bet you can't do this!! *grins* 65! 65! 65! 65!

Man: *annoyed* what the, hey... stop that! you think I can't do that huh?

Kid: 65! 65! Bet you can't do this mister! 65! 65! Haha!

Man: Why you.. *gets the kid off the makeshift trampoline and stands on it instead*

Man: I'll show you.. 65! Sixty...WHOAAAAAAAAHHHH!!

The kid stood there grinning, gets another sheet and covers the well. and continues..

Kid: 66! 66! 66! Hahaha!

Tragic... you thought it would be funny but it's disturbing...
