I was going to say something about a "barking lot" but decided against it. I wish I had thought of "impound lot." Good one!
I remember a Dave Berg cartoon in an old issue of Mad. A man driving a car with his wife in the passenger seat says, "That crazy dog is chasing our car again. Why do dogs chase cars? I'm going to stop the car and let him think he caught it. We'll see what he does." (The dog is not shown.) In the last panel, the man and woman are scowling and the man says, "Well, now that we know, let's go find a car wash."
