Here is another one...

A millionaire wins a rather messy divorce so to celebrate, he takes all his friends, and his lawyer, for a tip-top alcohol and sex-fuelled cruise on his private yacht round the caribbean.

The lawyers gets a little tiddly and manages to fall overnight. The crew throw him a life preserver and a banana dacquiri and he is happy as larry, bobbing about in the waves drinking whilst the rescue boat is launched.

Suddenly, this giant man-eating shark comes racing up to the lawyer, everybody is expecting him to be ripped apart but the shark surfaces underneath him so that the lawyer is astride his back, swims over to the side of the yacht and helps the lawyer back on board, with a wave from a fin and a flick of his tail, the shark disappears back into the depths.

Everybody is astounded and the millionaire walks up to the lawyer, who is still sipping his banana dacquiri happily, and asks him why the shark didn't eat him, but instead, helped him back on board.

"Oh that" says the lawyer "that is just professional courtesy"
