My urologist was hilarious about the entire vasectomy procedure. He has a thick accent, being Chinese, and made the whole thing somewhat fun - if fun can be used to describe a knife applied to an area men don't like to think about knives applied to.
On the day I went to get my consultation, he said "You look a little young to be getting this procedure." Thick asian accent, thick glasses. Then he looked at his clipboard and back at me over the glasses, "Ahhh, but you're not that young are you." He then checked my prostate and declared "There's no reason to tip me for that! I'll just bill you."
On the day of the vasectomy, my doc had given me valium so that I would be calm and perhaps to avoid me running from the room screaming. During the 'procedure' (if it's done to someone else it's a 'procedure,' if it's done to you it's 'surgery' - I call call it a procedure now because it's in the past), the doctor informed me that I would need to have '12 good clean ejaculates' before I could start bringing him samples to test. My vasectomy was on a Friday. Joking with the doctor, I said, "I'll bring you a sample on Tuesday."
Two weeks later when I go for the follow-up he asks me if I have had 12 good ejaculates and if I've brought him the sample. I shake my head no, and he goes "Ahh, but you talk so big when you have the procedure, but you didn't bring me the sample!"
