This week it's our Bonus Joke Show. Talk about hard work. We're always swimming in new jokes -- of every conceivable kind, sent to us from comedians all around the world -- and we make it our task to decide which ones are the winners. The returns are in: Join us with humorist Roy Blount, Jr., fiddler and saxophonist Andy Stein, and folk singer and guitarist "Spider" John Koerner.
