Dick: Oh, hello, Mary. I was just thinking about how long I've known you. Ten long years.
Mary: It's more like three years.
Dick: Well, then you'd be comfortable saying seven long years?
Mary: No, it's three years, Dick.
Dick: So I can safely quote you as saying that you've known me for six good, verifiable years, then?
Mary: Three.
Dick: Fair enough. But you are quite familiar with what I was doing in the three years prior to that?
Mary: Are you kidding me? You never told me anything about your life before you started working here. You hem, you haw, you rush in, you rush out. Oh, let's not forget the spontaneous laryngitis.
Dick: That was going around.
