At a small pub near to a GP's practice, Dr. Hall who ran the practice used to call into the pub after he'd shut the practice for the night and have an Almond sprinkled Jackory. One particular night, Bill the barman calls the landlord, "Mr. West, we're out of almond, and Dr. Hall's after his almond jackory, anything taste like almond what we could use instead?" Use hickory, the landlord said
Bill heads back to the bar, and speaks to Dr. Hill, We're out of almonds, but instead I could give you a "hickory jackory doc."
