Billy's Joke on Tuesday completely fell flat.
Our man Nick Riewoldt stuck around for the end of the show, and that included the sign-off with Billy's Joke.
Did Billy save his best for Roo? Not really.
"You came all the way back from Wyoming for that?!" JB exclaimed.
So Roo saved the joke with one of his own, right on the spot.
"That saved your joke!" JB laughed.
