Quote from Kripke in the episode Spoiler: Bert Gets Married
Kripke: I suppose it's technically possible for a society to develop Engwish as a wanguage without an Engwand, but it seems unwikewy. Denise: That's what I said. Stuart: Guys! Kripke: Of course, we could be speaking their wanguage and not know it. Denise: I said that too. Stuart: Listen to me! Kripke: [to one of the women in the hot tub] Ooh, not so wough on the tushy. Stuart: I've been through the whole village. There's one piece of red quartz, and Gavel won't give it up. Kripke: Ah, I'm not surprised. He's also a very selfish wover.
