Joke

A doctor made it his regular habit to stop off at a bar for a hazelnut daiquiri on his way home. The bartender knew the doctor's habit and would always have a drink waiting. But one day the bartender ran out of hazelnut extract, so he substituted hickory nuts. When the doctor arrived, he took a sip and exclaimed, "This isn't a hazelnut daiquiri!"

"No, I'm sorry," the bartender replied. "It's a hickory daiquiri, doc."
