A test for being drunk
A police officer pulls over this guy who had been weaving in and out of the lanes.

He goes up to the guy's window and says, "Sir, I need you to blow into this breathalyzer tube."

The man says, "Sorry officer I can't do that. I am an asthmatic. If I do that I'll have a really bad asthma attack."

"Okay, fine. I need you to come down to the station to give a blood sample." "I can't do that either. I am a hemophiliac. If I do that, I'll bleed to death."

"Well, then we need a urine sample."

"I'm sorry officer I can't do that either. I am also a diabetic. If I do that I'll get really low blood sugar."

"Alright then I need you to come out here and walk this white line."

"I can't do that, officer."

"Why not?"

"Because I'm too drunk to do that!"

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?!?"
