Paddy and Murphy

Paddy and Murphy are havin' a pint in the pub, when some scuba divers come on the TV. 

Paddy says, "Murphy, why is it them that the deep-sea divers always sit on the side of the boat with them air tanks on their backs, and fall backwards out of the boat?" 

Murphy thinks for a minute then says: 

"That's easy. It's 'cos if they fell forwards, they'd still be in the friggin boat!"
