After the fall in Garden of Eden...
After the fall in Garden of Eden, Adam was walking with his sons Cain and Abel. They passed by the ruins of the Garden of Eden. One of the boys asked, "What's that?" Adam replied, "Boys, that's where your mother ate us out of house and home."

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."
