Quote from Jim in the episode An Old Mustang
Georgie: This is gonna be great. I ain't never rode in a convertible before. Jim: You know how dogs like to stick their head out the car window? It's like that but for people. Georgie: Interior's in good shape. Seats leather? Jim: No, I think it's Naugahyde. Georgie: What animal's that from? Jim: I don't know, a... a "nauga"?
