A fraud in an ascot

RAY: If you look carefully you will see that the clue is in the phrase "my wife has gone shopping with my oldest daughter." You see he has only two daughters and an English professor would hardly make the mistake of saying oldest -- you'd have to have three or more.

TOM: Yes.

RAY: Having only two, she would be the older daughter. And, of course, this teller knew that he could not have been an English professor from Northwestern or from any place...

TOM: So she said, "Get the heck out of here!"

RAY: Get out you bum! And our winner this week is...?

TOM: Susan Edwards from Helena, Montana. Montana? We picked a winner from Montana?

RAY: No, we didn't. It's random.

TOM: Just to prove that it's random.

RAY: Right.
