A doctor stopped in at his favorite watering hole on his way home, as was his custom, and asked the bartender for his "usual" - a strawberry daiquiri. The bartender said that he was out of strawberries but would the doctor like to try a new flavor. He brought the alternate drink and upon tasting it the doctor said it was very good, what flavor is it? The barkeep replied, "It's a hickory daiquiri, Doc."
