This is a story that is attributed to Buddy Hackett. It sort of goes like this. There was a man, Bill, who had a penis that was a bit larger than normal. He found himself suffering from priapism (you can do a google search on this) for several hours, so he put on a trench coat to hide his condition and went to a pharmacy to find out if there was anything that he could take to ease the pain. He went to the pharmacy counter and asked the woman there if he could speak to the pharmacist. The woman replied that she was the pharmacist. Bill then asked if there was another pharmacist on duty. The woman replied that yes there was but that her sister was busy in the back room filling perscriptions. Bill, who was in fairly severe pain, then asked if there was a male pharmacist he could speak to. The pharmacist said there wasn't and she explained that she and her sister were the only pharmacists and they were also equal partners in owning the pharmacy. She then explained that both she and her sister were both competent pharmacists and would be able to help him with whatever he needed. Being in pain, Bill opened the trench coat and explained that he had been in this condition for several hours and asked the pharmacist what could she give him for it. The pharmacist took a look at his condition and then said she needed to consult her sister. She went to the back room and soon returned with her sister who also took a look at Bill. The two sisters were in a deep discussion for a while and then finally the the sister that Bill had first spoken to turned to him and said that they could give him $500 for the both of them.
