So who uses this site to mess with their friends? It's pretty fun. I've used it at school and I've scared my teachers. You punch in the answer in the petiton box (by first putting a period, and because of it's coding in puts in "Peter, please...") and then put the question. It's a great practical joke, especially when your friend reads too far into it.
I....don't get it. Seems overly complicated and kinda stupid. In my day just use to egg, tepee houses, and occasional flaming shit-in-a-bag for practical jokes.
