Irish Drunk Driver

One night, a policeman spotted a man driving very erratically through the streets of Dublin.

He pulls him over and asked him if he had been drinking that evening.

 "Aye, so I have," says Pat. 'Tis Friday, you know, so me and the lads went 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."

Pat continued, "Then I had to drive me friend's home and O' course I had to go in for a couple of Guinness, couldn't be rude, ye know. Then I stopped on the way home to get another bottle for later."

Pat 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, Pat said, "Why? Don't ye believe me?!"
