Dentist

A man goes to an oral surgeon to have a tooth pulled. The dentist
pulls out a freezing needle to give the man. "No way! No needles! I
hate needles!" the patient said.

The dentist starts to hook up the laughing gas and the man again
objects. "I can't do the gas thing - the thought of having the gas
mask on is suffocating to me!"

The dentist then asks if the man has any objection to taking a pill.
"No objection", the patient says, "I am fine with pills". The dentist
left for a moment and when he returned, says "Here is a Viagra
tablet." The patient says, "Wow - I didn't know Viagra worked as a
pain killer!"

"It doesn't," said the dentist, "but it will give you something to
hold on to when I pull out your tooth."
