Trip to the doctor

A man went to visit his doctor because his arm is hurting.

"Doc, my arm hurts real bad. Can you check it out please?" the man pleads.

The doctor rolls up the man's sleeve and suddenly hears the arm talk.

"Hello, Doctor" says the arm. "Could you lend me twenty bucks please? I'm desperate!"

"Aha!" says the doctor. "I see the problem.

Spoiler:

Your arm is broke!"
