The doctor said, "OK. Touch your elbow." The guy touched his elbow and winced in genuine pain. The doctor, surprised, said, "Touch your head." The guy touched his head and jumped in agony. The doctor asked him to touch his knee and the same thing happened.

Everywhere the guy touched he hurt like the dickens. The doctor is stumped and orders a complete examination with X-rays, etc. and told the guy to come back in two days.

Two days later the guy came back and the doctor said, "We've found your problem."

"Oh yeah? What is it?"
