After several kids, a guy decides to get a vasectomy. He's a little nervous about it but after talking to his personal physician about the procedure, he schedules the surgery. The day arrives and he is wheeled into the operating room. Although still a little nervous, he slips under sedation.
After surgery he awakens in the recovery room and there are a number of Doctors and Nurses standing around with a worried look on their faces. What's wrong" he asks?. The Doctor replies "Well, we had a little mix-up in the OR". "It seems that in an adjoining room, we had a man in for a sex change operation and it seems that we accidentally gave him the vasectomy and you the sex change" The patient is astounded but after a moment he asks the Doctor, "you mean that I won't be able to experience an erection anymore?" The Doctor replies "well yes, it just won't be yours."
