An offense
Late one Friday night the policeman spotted a man driving very erratically through the streets of Dublin. They pulled the man over and asked him if he had been drinking that evening."Aye, so I have. 'Tis Friday, you know, so me and the lads stopped by the pub where I had six or seven pints. And then there was something called "Happy Hour" and they served these mar-gar-itos which are quite good. I had four or five o' those. Then I had to drive me friend Mike home and O' course I had to go in for a couple of Guiness - couldn't be rude, ye know. Then I stopped on the way home to get another bottle for later .." And the man fumbled around in his coat until he located his bottle of whiskey, which he held up for inspection.The officer sighed, and said, "Sir, I'm afraid I'll need you to step out of the car and take a breathalyzer test."Indignantly, the man said, "Why? Don't ye believe me?!?"

A rabbi, a priest, and a lawyer were all...
A rabbi, a priest, and a lawyer were all caught in a shipwreck. Naturally, there are a lot of sharks circling around. All of a sudden, one shark darts in and grabs the priest for lunch. No more priest.
The rabbi starts praying frantically, but to no avail, as a shark comes in and eats him, too.

Now the lawyer is really worried, as a shark is coming for him. But, miracle of miracles, the shark puts him on its back, carries him to shore, and lets him off.

The lawyer, curious, waits till the shark is far enough away not to eat him, and asks, "How come you didnt eat me?" And the shark replies, "Professional Courtesy!"
