Rolling Stone

There was the head of a small construction firm named Sisyphus - the man, not the firm, and he was asked to put in a quote for a job which involved the pushing of a large boulder up a hill, but- and here was the catch - the boulder would, and noone could satisfactorily explain why, invariably fall back down the hill it had just come up, from where it would have to be pushed back up the hill again, from where again it would... only to... and so on. Sisyphus was in two minds. "We could do with the work, no doubt, but hell, we'll have to charge an awful lot. It's gonna take forever."
