>>Repeatedly performing action X and repeatedly getting result Y and then performing action X and expecting a result that is not equal to Y is pretty stupid, period.
I'd also heard that poking a wire into a power socket is fairly stupid, as is trying to thread a knitting needle through one ear and out the other or not escaping immediately if a girl asks "does this make me look fat".
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
