A man went to the dental surgeon to have a tooth pulled.
The dentist pulls out a freezing needle to give to 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 an objection to taking the pill. "No", the patient says, "I am fine with pills". The dentist returns and says, "Here is a Viagra tablet".
The patient says, "Wow, I didn’t know that Viagra worked as a pain pill!".
It doesn’t said the dentist, "It will give you something to hold on to when I pull out your tooth".
