This is one of my favorite jokes and it always cracks me up, lol (the wording is not exactly like how I first read the joke).
A Jewish man, an atheist, and a scientist all jump into an airplane. The Jewish dude throws an apple out of the airplane, grabs a parachute and jumps down. When he lands, he sees a little boy crying. So, he's like, "Why are you crying little boy?" The little boy responds with, "An apple came out of nowhere and hit me on the head ." The atheist follows suit, by throwing a banana peel out of the airplane, grabbing a parachute and jumping out of the airplane. When he lands, he sees a little girl crying. So, he sympathetically asks, "What's up? Why so sad?" The little girl says, "I slipped on this banana peel!". As for the scientist, he throws a bomb out of the airplane, grabs a parachute and jumps. When he lands, he sees a little boy laughing hysterically. So, he asks, "What's so funny?" The boy chuckles and says, "I farted and my house blew up!"
