Quote from Robert in Pat's Secret
Robert: So you mind if I bum a ciggy? Pat: You want a cigarette? But you don't smoke. Robert: Oh, sure. As a cop, it helps to have a smoke every so often, 'cause I gotta tell you, I see a lot of sick things every day. You know, I once found a foot in a mailbox. Pat: Oh, my. Robert: Oh, yeah. Luckily, we caught the guy 'cause there was a return address. It's a cop joke.
