Fwd: Going to the Dentist

Rico says his friend Tex sends this:

The dentist pulls out a numbing needle to give his patient a shot of Novocaine.
"No way! No needles! I hate needles!"
The dentist starts to hook up the nitrous oxide, but 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 says: "Here's a Viagra."
The patient says: "Wow! I didn't know Viagra worked as a pain killer."
"It doesn't," said the dentist, "but it's going to give you something to hold on to when I pull your tooth.
