Billy's Joke gets a hell of a lot more inappropriate on a Friday.
And this one's no exception!
The joke about naughty little Johnny - in a rare feat - actually left JB and Rabs laughing plenty.
Not because it was necessarily the greatest joke of all time.
But because Billy slaughtered it!
"Little Johnny was asked by the teacher, 'Johnny, can you tell me the names of the three great kings...'"
