Quote from Bert in the episode Spoiler: Stuart Makes a Wallet
Stuart: Well, we're not in Pasadena. Denise: Is it real? Bert: Seems real. Sand, organic material, clay. Could be kaolinite or montmorillonite. Kripke: What's that mean? Bert: It's dirt. Kripke: Why didn't you just say "dirt"? Bert: I was showing off a little.
