Quote from Woody in What Is... Cliff Clavin?
Cliff: Hey, guys. Guess what. Jeopardy! is coming to town for a one-time only east coast appearance. And I'm going to take the test to be on the show. Woody: Beer, Mr. Clavin? Cliff: What is a brewed alcoholic beverage consisting of barley and yeast? Woody: Well, I don't know. Usually, you just have a beer.
