What memory cracks you up no matter how long ago it was?

For me, it was a long time ago in elementary school...this kid in my cl, (who was quite crazy) was holding a book with one of those reflective surfaces outside on a sunny day. Anyway, it reflected onto his nose, and someone else said, "There's something on your face!", and he yelled and hit himself in the face with the 1000 page book, giving him a nose bleed. What made it even funnier is that he was this puny redheaded freckly kid.
