A man went to the dental surgeon to have a tooth pulled. The dentist pulls out a freezing needle to give the man a shot. "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 a gas mask on is suffocating to me."
The dentist then asks if the man has any objection to taking a pill. "No," the patient says, "I am fine with pills.
The dentist then returns and says, "Here is a Viagra tablet."
The patient says, "Wow, I didn't know Viagra worked as a pain pill!"
"It doesn't," said the dentist, "but it will give you something to hold onto when I pull out your tooth!"
