We always had a saying, bad shit happens. Doesn't matter what precautions are taken, how many safety devices there are, how many procedures are in place, sooner or later bad shit happens. Want to make sure bad shit happens, just utter one of the following statements: what could possibly go wrong; what could go wrong next; nothing else could possibly go wrong. Ask and ye shall receive.
A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools.Nothing is foolproof to a sufficiently determined fool.
