A man goes to a dentist to have a tooth pulled. The dentist pulls out a freezing needle to give the man. "No way! No needles! I hate needles!" the patient yelps. The dentist starts to hook up the laughing gas and the man again objects. "I can't do the gas thing. The
thought of having the gas mask on is suffocating to me!" The dentist then asks if the man has any objection to taking a pill. "No objection" the patient says, "I'm fine with pills." The dentist then returns and says, "Here's a Viagra tablet." The patient says, "Wow - I didn't know Viagra worked as a pain killer!" "It doesn't," said the dentist, "but it'll give you something to hold onto when I pull out your tooth."
