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 Hot Day
It was a stifling hot day and a man fainted in the middle of a busy intersection.

Traffic quickly piled up in all directions, so a woman rushed to help him.

When she knelt down to loosen his collar, a man emerged from the crowd, pushed her aside, and said, "It's all right honey, I've had a course in first aid."

The woman stood up and watched as he took the ill man's pulse and prepared to administer artificial respiration.

At this point she tapped him on the shoulder and said, "When you get to the part about calling a doctor, I'm already here."
