A man goes to the dentist...

A man goes to the dentist to get a tooth pulled. As he's laying in the chair for the operation, the dentist pulls out a needle to numb him.

The man says, "No man, I deathly afraid of needles."

So the dentist pulls out the gas to put him under.

The man says, "please don't, I'm very claustrophobic."

So the dentist finally pulls out two blue pills and hands them to the man.

The man says, "I didn't know Viagra was a pain reliever."

The dentist says, "It's not, but at least you'll have something to hold onto while I pull this tooth!"
