Ledeczi Algorithm

A geeky but amusing memo that was hanging on the back of a stall door in the bathroom at the institute at which I work.

void Number2 (Toilet &t) {
    if (!t.stall.occupied()) {
        t.stall.lock(true);
        t.seat = down;
        SitDown(t);
        ProduceOutput(t);
        StandUp(t);
        t.Flush(t);
        while (!butt.clean) {
            Paper p;
            t.stall.GetPaper(p);
            WipeBehind(p);
            t.Put(p);
        }
        t.Flush();
        t.stall.lock(false);
    }
}
