A man goes to a female dentist
A man goes to a female dentist to have a tooth extracted. She pulls out a large syringe to give him an anesthesia shot.
"No way, no needles! I hate needles!" the man exclaims.
So she starts to hook up the nitrous oxide tank, and the man says, "I can't do the gas thing either. Just the thought of having a mask on my face suffocates me!"
The dentist then asks the patient if he had any objections to taking a pill. "No," he says, "I'm fine with pills." So the lady dentist gives him two little blue pills and he swallows them. "What are those?" he asks. "Viagra," she calmly replies.
"I'll be damned," said the man, "I didn't know Viagra works as a pain killer."
"It doesn't," says the wise lady, "But it'll give you something to hold on to when I pull your tooth."
