A doctor walks into a bar after a long day at work, sits down, and orders a pecan daiquiri. The bartender nods and gathers up the ingredients and starts mixing up the concoction. However, he quickly discovers that he had no more pecans left to add to the drink. After searching high and low behind the bar, he eventually finds some hickory nuts from one of the many Christmas decorations littering the bar. So, he substitutes them into the drink and serves the drink to the doctor. The doctor takes one sip, wrinkles his nose, and says to the bartender, "This isn't a pecan daiquiri...what is this?". "Well," the bartender responds, "That's a hickory daiquiri, doc."
