But we’re wondering  is crying “Rat!” actually a semi-original very New York City way to get the best seat on the bus  or to avoid standing next to a chatty passenger? Is crying “Rat!” akin to crying “Fire!” in a crowded theater? Or is crying “Rat!” more like crying “Wolf!”? Would you have the presence of mind to scream “rat” if you actually saw a rat  or would you simply scream  jump in the air  and possibly pee yourself a little?
