I heard this on the Buzz this morning and laughed for a good minute...guess you gotta hear it or read it out loud to get it.

GIRL: I'm here for my breast exam...
DOCTOR: OK. I will need you to get undressed.

Girl says OK and gets undressed.

DOCTOR: OK. First we are going to numb your breasts.
GIRL: OK.

Doctor sticks his head between her boobs and go's....

DOCTOR: numb.numb.numb.numb.numb.numb

lol probably a retarded joke, but I enjoyed it.
