Some guy came up to my friend and he was carrying 3 cups and a ball. And he asked my friend if he wants to bet 5 dollars on that game where he shuffles the cups and you guess where the ball is.
1st game: The guy makes it pretty easy and my friend wins 5 dollars.
2nd game: My friend loses 5 dollars.
3rd game: My friend loses 20 dollars.
4th game: My friend loses another 20 dollars.

Did I mention my friend was rolling pretty hard?

Moral of the story: avoid wagering money on carnival games if you have taken ecstacy.
