I remember using a friend's calculator when I was a kid- the kind with the big side crank. Every time you pulled it, you felt like you were about to hit the jackpot. It made me think being an accountant must be the best job ever! Plus there was the bonus of the incredibly long roll of paper, which she never tore off, just kept piling up. When she was looking for a particular transaction she would swish the roll through her hands, in a very exuberant fashion. Who says accountants are boring?
