The female dentist pulls out a numbing needle to give the man a shot.

“No way! No needles! I hate needles!” says the patient.

The dentist starts to hook up the nitrous oxide, and the man objects.

“No way! I can’t do the gas thing. The thought of having a mask on suffocates me!”

The dentist then asks the patient if he has any objection to taking a pill. “No objection at all,” the patient says.

“I’m fine with pills.

” The dentist then returns and says, “Here’s a Viagra.”

The patient says, “Wow! I didn’t know Viagra worked as a pain killer!”

“It doesn’t,” said the dentist, “but it’s going to give you something to hold on to when I pull your tooth.”
