During the initial space flights, Nasa discovered that biro pens didn’t work under zero gravity conditions. To beat the problem, Nasa spent 6 years and $2 million in designing a pen for use in space. The pen would work under zero gravity conditions due to the pressurized ink inside, it would work under sub zero conditions, underwater, on glass and virtually any surface known to man. The Russians used a pencil.

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."
