Quote from Norm in What Is... Cliff Clavin?
Norm: Can I have another beer, please? Rebecca: I don't see any money, Norm. Norm: Yeah, yeah. I really should go hit that bank machine, I guess, but, um, but I hope on the way out I don't happen to just inadvertently mention that one thing that Carla and I happen to know about you. Rebecca: Shut up, Norm, and drink your free beer. Norm: [to Carla] This bluffing thing is a gold mine. Carla: Yeah, I've given you a wonderful gift, my son. You must use it for good only, never for evil. Norm: Free beer is good, right? Carla: You learn fast, young Norm.
