First off, we have to deal with Mister King Train Loving Dentist Man and his bad attitude about the whole project. It seemed almost karmic that a pompous buffoon whining about the horrible horror of him, John Patterson, being COMMANDED by an infant who should have been forced to man up and use a strange commode to break into a locked house and grab onto a potty like a fool be held by the fuzz on a breaking and entering beef. Watching the dreary moron wail like the idiot he is about how everyone is actually laughing at him would almost be a source of pleasure were it not a reminder that he thinks that being laughed at is a sign that he's weak and bad and weak but also that anyone who inconveniences him is clearly out to destroy him.
This leads us to the real problem: the inability (or, more properly, refusal) of the Pattersons to admit that there isn't always a bad guy who wants to hurt them because they hate them when something bad happens. You and I see a frightened child who doesn't and can't know what the results of his panicky refusal to go where he doesn't want to go are. John sees a monster who wants to see him with his pants down because the alternative is really scary. John needs to see monster children who want to defy him and make him a slave to their cruel drama because the idea of well-meaning children who don't want to hurt him but still make good-faith mistakes means that instead of a reasonable, calm and cool straight-shooter, he's a thin-skinned, vain and hostile mess picking on people for the unworthy reason of making him look bad.
