The Minister, the Doctor, and the Plumber
RAY: Only one of them could have been named Frank, because the other two, the plumber and the doctor, were women.
TOM: I was married to a Frank, once.
RAY: Don't go there. Who's our winner this week, Tommy?
TOM: Our winner today is Frank -- Mrs. Frank -- No, our winner is Robert Mandela. And for having his answer selected at random from among those thousands of correct answers that we got this week, Robert is going to get the usual; a twenty-five dollar gift certificate to the Car Talk Shameless Commerce Division.
