Policeman: If that creep over there is who I think he is, you're in a lot of trouble, bud! Mike: Who-Mr. Jay? Don't worry, officer...Mr. Jay is just a simple figment of my imagination! Policeman: Oh, really? Well, I got news for you, ace! So am I! Mike: Do you know a good shrink? J.J.: Yes, but she smokes.
