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."

A serious condition
A well respected surgeon was relaxing on his sofa one evening just after arriving home from work. As he was tuning into the evening news, the phone rang. The doctor calmly answered it and heard the familiar voice of a colleague on the other end of the line."We need a fourth for poker," said the friend."I'll be right over," whispered the doctor. As he was putting on his coat, his wife asked, "Is it serious?""Oh yes, quite serious," said the doctor gravely."In fact, three doctors are there already!"
