Quote from Tim in The Tool Man Delivers
Tim: I might need a lift to my car if it's OK. Ned: Well, I could give you one. But we might suddenly get busy. Tim: And I might suddenly become a ballet dancer. Ned: Forget it, pal. You don't have the legs. Tim: Can I use the restroom now? Ned: Yeah. It's over there. Unfortunately, it's out of order. Tim: [exhales] You might've mentioned that to me before. Ned: Why? You weren't a customer then.
