A man went to the dentist because his tooth was hurting.
The dentist told him after the examination that he need a root canal.
The man replied “O.K. lets do it”.
The dentist told him he will feel a pinch when he gives him the shot of the numbing agent.
The man says “NO Doc I am allergic to that”.
The doctor tells him O.K. we are going to give you Nitrous Oxide.
The man says “No Doc I am allergic to the gas.”
So then the doctor gives him 2 pills with a glass of water & the man takes it.
The doctor comes back in 10 minutes & the man says “Doc will those 2 blue pills kill the pain?”
The doctor replies “no, that was Viagra.”
The man says “Viagra!, I don’t need that! What’s that going to do for me?”
The doctor replies, “I know, But it will give you something to hang on to”.
