Billing
A doctor and a lawyer were talking at a party.
Their conversation was constantly interrupted by people describing their ailments and asking the doctor for free medical advice.
After an hour of this, the exasperated doctor asked the lawyer, "What do you do to stop people from asking you for legal advice when you're out of the office?"
"I give it to them," replied the lawyer, "and then I send them a bill."
The doctor was shocked, but agreed to give it a try.
The next day, still feeling slightly guilty, the doctor prepared the bills.
When he went to place them in his mailbox, he found a bill from the lawyer.
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."
