Norm: Kelly, can I have a beer, please?
Kelly: Okay, let me go get Woody.
Norm: Oh, no, you don't need Woody. Come here. I'm gonna show you how it's done. Take a glass, stick it underneath this black lever here, okay? Voila, you have a beer. Now there's a, uh, black book underneath the cash register. It says "Norm's tab" on it.
Kelly: You mean this one here with all these little marks?
Norm: Right. Now, Kelly, each one of these little marks represents a beer that I've purchased in advance. Every time I order one, you have to take this eraser and, uh, erase one of those little marks. Don't forget to erase now. I don't want any free beers!
Kelly: Okay, Mr. Peterson.
Norm: Thank you.
Cliff: Unbelievable! I'm in the presence of sheer genius.
Norm: Thank you, Cliffy. Kelly, can I have another beer for my dear friend Clifford Clavin? And what the heck, take it off my tab.
