This reminds me of a Joke I have known since High School
The delivery is very important, so hopefully you can visual me telling this joke
A lady goes to the Gynecologist. After she gets undressed and onto the table and stirrups, the Dr. comes in.
He says, "Hello Maim, before we get started I am going to have to Numb this."
The patient replied "Of Course Dr. do whatever is necessary"
So the Dr. dives in head first
