I had one job that was so routine that a trained monkey could have done it. Heck, a politician could have done it, with coaching. In order to relieve the tedium I used to have races with myself to see how much I could get done in any particular hour. It was probably good for the boss and gave me a little entertainment. (It didn't make me popular with some of the people I was working with, but a man's gotta do what a man's gotta do.)
