John goes to the doctor and says, "Doc, I ache all over. Every where I touch it hurts."

The doc says, "Ok, touch your elbow."

John touches his elbow and winces in genuine pain.

The doc, surprised, says, "Touch your head."

John touches his head and jumps in agony. The doc asks him to touch his knee and the same thing happens. Everywhere John touches it hurts like hell. The doc is stumped and orders a complete examination with X-rays etc and tells John to come back after two days.

Two days later John comes back and the doctor says, "We've found your problem..."

"Oh yeah? What is it?"

"You've broken your finger!"
