Quote from Kripke in the episode Spoiler: Bert is Magic
Stuart: Where have you been? Kripke: [with rhotacism] Wooking everywhere for you. Stuart: Have you seen Bert? Kripke: I have not. I have not seen Bert, no. Stuart: Should we be worried? Kripke: Were you worried about me? Stuart: Not really, no. Kripke: Well, there you go.
