Doctors Daiquiri

A Doctor made it his regular habit to stop at a bar for a hazelnut daiquiri on his way home. The bartender knew of his habit, and would always have the Doctors drink waiting for him at precisely 5:03 PM. One afternoon, as the end of the workday approached, the bartender was dismayed to find that he was out of hazelnut extract. Thinking quickly, he threw together a daiquiri made with hickory nuts and set it on the bar. The Doctor came in and took a sip of the drink and exclaimed, "This isn't a hazelnut daiquiri!" "No, I'm sorry," replied the bartender..."It's a hickory daiquiri, Doc."
