Sex Karma

A cheap tourist in a south of the border town known for prostitution picks up a hooker. After paying her, he drives off, shouting back, "El dollar, counterfeito!"
The prostitute smile and shouts back, "El syphilis, originale!"

The Mugger Payback

Two guys are walking down a dark alley when a mugger approaches them and demands their money. Both scared, they pull out their wallets and begin taking out their cash. Just then, one guy turns to the other and hands him a bill and says, "Hey, here's that twenty dollars I owe you."

The Massage!

In a long line of people waiting for a bank teller, one guy suddenly started massaging the back of the person in front of him. Surprised, the man in front turned and snarled, "Just what the hell you are doing?!"
"Well," said the guy, "you see, I'm a chiropractor and I could see that you were tense, so I had to massage your back. Sometimes I just can't help practicing my art!"
"That's the stupidest thing I've ever heard!" the guy replied. "I work for the IRS. Do you see me screwing the guy in front of me?"
