A man goes to a female dentist because he needs a tooth pulled. The dentist pulls out a large syringe to anesthetize his mouth and jaw. "No way, no needles! I hate needles," the man replied. So the dentist start to hook up a nitrous oxide tank, and the man says again, "No way. I can't do the gas thing either. Just the thought of having a mask on my face suffocates me!"
The dentist smiles and asks him, if he had any objections to taking a pill. "No," he replies, "I'm fine with pills." So she pulls out two blue pills and gives them to him to take, and he does so.
After he swallowed them, he asks, "What pills are these?"
"Viagra," she replied.
"I'll be damned," replied the man, "I didn't know Viagra worked as a pain killer too!"
"It doesn't," she said, "but it'll give you something to hold on to while I pull your tooth!"
