Umm well actually, to be quite frank, it needs a bit of polishing and a punch line. ( but never mind you had a go and a lot of comedy is trial and error ,so don't give in )
A man went to a dental surgeon to have a tooth pulled.
The dentist pulls out a freezing needle to give the man. No way! No needles! I hate needles! The patient said.
The dentist starts to hook up the laughing gas and the man again objects.
I can't do the gas thing - the thought of having the gas mask on is suffocating to me! The Dentist then asks if the man has any objection to taking a pill. No, the patient says, "I am fine with pills."
The dentist then returns and says, here is a Viagra tablet.
The patient says, Wow - I didn't know Viagra worked as a pain pill.
It doesn't, said the dentist, but it will give you something to hold onto when I pull out your tooth.
