I came across these jokes on Scatty.com:
Friar Tuck was a monk, so why did he get involved in a life of crime?
It was his habit!
How did Robin Hood tie his shoe-laces?
With a long bow!
Knock, knock- Who's there?
Robin the rich to give to the poor!
What did Robin say when he nearly got hit at the archery contest?
"That was an arrow escape"!
