Haha, all these are pretty funny
Here's one a remember from a long, long time ago:
Three people once found a magic slide that gave you whatever you shouted to it as you slide down. The first man yelled "Gold!" and landed on a stack of gold. The second person shouted "Money!" and landed in a pile of money. As the third person slid down, he yelled "WEEEEEEEEEEE~!" and guess what? He landed in a pool of wee.
