I convinced a younger cousin he could fly off the house with a chicken feather in each hand, he broke both ankles.
we duct taped an older kid to a tree out in the woods once, left him till a little after night fall. (City kid knew nothing of teh country noises)
Took a young kid "snipe" hunting walked him nearly 2 miles from my uncles house in an area he was unfamiliar with, he made it back teh next morning.
The story's could go on and on.. but at some point it would likely get me in trouble.
The Moral of the story:
kids can be cruel, especially to other kids that cause them trouble.
