The Dentist

A man goes to an oral surgeon to have a tooth pulled. The Dentist pulls out a freezing needle to give the man a shot. 'No way! No needles! I hate needles,' the patient said.
The Dentist starts to hook up the laughing gas and the man objects.
'I can't do t he gas thing. The thought of having the gas mask on is suffocating 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 tablet.'
The patient says, 'Wow! I didn't know Viagra worked as a pain killer!'
'It doesn't', said the Dentist, 'but it will give you something to hold onto when I pull your tooth.'
