One day a couple of young boys went into a dentist's office. One of them told the receptionist that he wanted to have tooth pulled but didn't want to have any Novocain, gas, or any other medication. They were in a hurry and couldn't afford expensive medication.
The dentist agreed. He turned to the little boy and asked, "OK, which tooth is it that is bothering you?"
At that the little boy turned to his younger companion and order,
"Open your mouth, Billy, and show the doc which tooth hurts!"
