The female dentist pulls out a numbing needle to give the man a shot......
"No way! No needles. I hate needles" the patient said.
The dentist starts to hook up the nitrous oxide and the man objects.
I can't do the gas thing. The thought of having the gas mask on suffocates Me!!
The dentist then asks the patient if he 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."
The patient says, "Wow, I didn't know Viagra worked as a painkiller"
"It doesn't" said the dentist, "but it's going to give you something to hold on to when I pull your tooth".
