(I'm not sure how well this will come across as it is a rather aural joke. One that doctors and nurses love.)
A young lady is at a doctor's office, her first visit to a new OB-GYN (women's doctor for those who don't know.)
The nurse has gotten her in her gown and seated her on The Table, her feet in the stirrups in that most lady-like pose that women hate and Hustler loves.
In walks the doctor, mature, handsome and wise-looking. He perfunctorily greets her after glancing at her chart, seats himself on the low stool at the end of the table and raises her gown to begin his examination.
As the nurse hands him the speculum (think of stainless steel scissor-type salad tongs), he says to the young lady, "Before we proceed, I need to numb you."
"Okay", she says.
