Al: Are you through joking around?
Tim: Yes. I was just trying to stay awake till we get to the good part. The tools. Al, tell us about the tools.
Al: All right, well, these are the tools of the trade when putting in carpet. What we have here is a porcupine roller, duckbill shears...
Tim: What? Are you laying carpet at the zoo?
Al: Yes, I'm carpeting the zoo. As a matter of fact, I'm thinking of putting in walrus-to-walrus carpeting. [audience laugh and applaud]
