Quote from Mike in A Very Donahue Vacation
Mike: All right, I'm going on a tour of the cave. Who's going with me? [nobody reacts] Anybody? No? Okay, you're gonna miss it. [later:] Tour Guide: [v.o.] You're now in the deepest recess of the longest cave system in the world. When I turn off this lamp, you'll experience a complete absence of natural light. Mike: Cool.
