Martha and George

Martha the Rock is a Koozebanian creature seen in The Muppet Show, Episode 319.

In the episode's two-part "Pigs in Space" sketch, the Swinetrek crew land on the planet Koozebane. They look around the surface briefly, and decide that there's no life on Koozebane. After they return to the ship, two nearby rocks come to life. The female rock says, "George, wake up! I think I hear prowlers." The male rock answers, "Oh, Martha, go back to sleep!"
