2 Mexicans
A Border Patrol agent is on duty. He spots two Mexicans and runs them down. They show him their papers (he thinks they are phony).

He tells them, "O.K. I have a test for you. I want you to use the words 'cheese' and 'liver' in a sentence."

So, the first guy says, "I made a liver and cheese sandwich for lunch."

The agent says, "That was good, you can go. What about you?" he asks the second guy.

He says, "Liver alone. Cheese mine."

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?!?"
