In yet another incoherent, rambling post, OM village idiot utsmith (tnsmith) stated that a styrofoam cup thrown from a moving vehicle can, in fact, kill a man. This was possibly in response to some Bama fans throwning something at him? Anyway, he later tried to edit the scenario in another post (a smithy trademark) and the stryfoam cup could kill if wrapped around a rock, or piece of ice.
