Mary: You know, I can't believe how flaky that sole was.
Dick: Mm. You know what I can't believe? That you've never been pregnant.
Mary: What?
Dick: Considering how many "gentlemen callers" you've had, it's kind of a miracle.
Mary: Dick, I can't have children.
Dick: Oh, Mary... why not?
Mary: Because I hate them.
Dick: Oh, well, we're okay then.
