Female Dentist.........

[Blackal]

The female dentist prepares the needle to give the bloke
with the toothache an anaesthetic injection.
“No way! No needles, I hate needles!” the guy said.
So the dentist starts to hook up her nitrous oxide gas
and the man objects again. “I can't do the gas thing either.
The thought of having the gas mask on my face makes me faint!”
She then asks the guy if he has any objection to taking a pill.
“No objection,” the patient says. “'I'm fine with pills.”
When she returns she says, “Here's a Viagra and a glass of water.”
The guy says, “Wow! I didn't know Viagra worked as a pain killer!”
“It doesn't” she said, "But it’ll give you something to hold on to while I pull your tooth out."

Go over that again.

I missed who's pulling what.
