Helicopter Fart
When me and my brothers were all little, my mother told us how she was waiting in line in a shop, and that a black man in front of her did a fart that went BA BA BA BUWEEET, and that she had to jump away to avoid it. I don't know what the fact that it was a black man had anything to do with the story, but we all found this to be so hilarious that it became known as The Helicopter Fart, and every time we farted we would try to recreate it.
