A little girl and a businessman are sitting next to each other on a plane.

The girl is reading, but the businessman is obviously getting bored. So, he says to her "ya know, talking is the best way to pass the time on a flight." The girl, showing slight annoyance, puts down her book and says "okay, what do you want to talk about?" He says "let's talk about religion, do you believe in God?" The girl answers "yes." "Well, I don't," says the man, "how could anybody believe that an invisible man who floats in the sky created everything?" The girl responds with "there are three animals, a rabbit, a horse, and a cow. The rabbit poops little pellets, the horse poops chunks, and the cow poops patties. Why is that?" The man hesitates, and says "I don't know." "Well," the girl says, "don't try to talk about God when you don't know crap."
