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 prisoner with skills
Several years ago, Andy was sentenced to prison. During his stay, he got along well with the guards and all his fellow inmates. The warden saw that deep down, Andy was a good person and made arrangements for Andy to learn a trade while doing his time. After three years, Andy was recognized as one of the best carpenters in the local area. Often he would be given a weekend pass to do odd jobs for the citizens of the community.... and he always reported back to prison before Sunday night was over.

The warden was thinking of remodeling his kitchen and in fact had done much of the work himself. But he lacked the skills to build a set of kitchen cupboards and a large counter top which he had promised his wife. So he called Andy into his office and asked him to complete the job for him.

But, alas, Andy refused. He told the warden, "Gosh, I'd really like to help you but counter fitting is what got me into prison in the first place".
