Monday: "Two Tens For a Five."

Bud Abbott and Lou Costello's firstscene in the movie 'One Night in theTropics' is a classic. Abbott cons Costello by simply askingfor change. "Have you got 2 tens for afive?" he asks. As Lou realised he has been duped, Bud snaps back: "OK, here's your five, give me back my 2 tens!" The skit carries on and Lou loses money! "Two Tens for a Five" is a classic vaudeville routine made famous by Bud Abbott and Lou Costello and has been repeated many times over the years.

dollars.
