A doctor worked on the tenth floor of an office building. In the building was a pub, where the doctor had a lemon daiquiri, every day at quitting time. The bartender's name was Dick.
One day, Dick discovered he didn't have any lemons and no time to get any. So he thought he would make up a hickory daiquiri instead and at the end of the day, perhaps the doctor would be too tired to notice.
The doctor sat down, took a sip and said "This isn't a lemon daiquiri, Dick!" To which Dick replied, "No, its a hickory daiquiri, Doc!"
