There's was this (humorous) TV show that was about a kid who went back in time, and met Davy Crockett. In one scene, Davy and his other pioneer friends see a comet in the sky. Not knowing what it is, they are puzzled. The kid says "Hey cool! Maybe it's a UFO, or maybe ET!" One guy with a slow Tennesee drawl says "Nope, I don't think it's an oofo OR an et!"
