Quote from Kripke in the episode Spoiler: Zack's in This One
Stuart: What's that? Bert: Best guess? A giant floating obelisk with no apparent means of propulsion? Kripke: [with rhotacism] You are weawy getting on my nerve. [The light on the obelisk turns red, as does the light on the device in Kripke's neck] Kripke: Stop talking. [Kripke groans as he once again tenses up and drops to the floor, writhing in agony] Stuart: Another piece of the puzzle? Bert: Maybe. [Kripke yelps]
