You have to wonder, at what point during this brief clip does the driver of the semi think, "This is a bad idea?" Is it before or after the railroad crossing gates close around him; before or after he tries to back his way out; before or after he tries to cross in front of a speeding train? Whatever the unknowable answer to that question is, the more amusing one is how long did it take him to clean his shorts out when it was all over? [YouTube ]
