A man goes to a female dentist to have a tooth extracted. She pulls out a needle to give him a shot of local anesthetic, but he says, “No way! I hate needles!” So she starts to hook up the nitrous oxide mask, and he says, “I can’t do that either. The thought of having the mask on suffocates me!” The dentist then asks the man if he has any objection to taking a pill. “No,” he says, “I’m fine with pills.” She returns with two blue pills. “What are those?” he asks. “Vi agra,” she replies. He says, “Wow! I didn’t know Vi agra works as a painkiller!” “It doesn’t,” said the dentist, “but it’ll give you something to hold on to when I pull your tooth.”
