I got this joke on email this morning, its so bad I just had to share it.
A doctor, made it his regular habit to stop off at a bar for a hazelnut daiquiri on his way home. The bartender knew of his habit and would always have the drink waiting at precisely 5.15 p.m. 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 Doc came in at his regular time, took one 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". !
Sorry I said it was bad
