The Female Dentist

She pulls out a numbing needle to give the man a shot.  "No way! No needles. I hate needles" the patient said. The dentist starts to hook up the nitrous oxide and the man says:" I can't do the gas thing. The thought of having the gas mask on suffocates me!' The dentist then asks the patient if he has any objections to taking a pill. "No objection," he says. "I'm fine with pills." The dentist gives him a couple of pills. He swallows them. "What are they?" he says. "Viagra," says the dentist. "Heck," the patient says, "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."
