Movie Rule #19294 - Men are physically incapable of changing diapers.
You ever notice in movies how men are never able to change diapers? If there's a man who has to take care of a baby and there isn't a woman around, there's the inevitable diaper-changing scene. The man/men struggle to figure out how to take off the diaper. Then the moment the diaper is opened, the man/men react as if they've just opened a vat of nerve gas. They gag, they flee, they put on masks, they use kitchen tongs to peel away the diaper, hose the baby down with a garden hose. And then they practically strangle the kid trying to figure out how to put the new diaper on. When was the last time you saw a man confidently change a baby? Replace the men with women and you'll see how silly that is. No, in the movies, women are born knowing how to change a diaper and are immune to any odors or distaste. In fact, you rarely even see a woman changing a diaper in a movie at all - it's just assumed that they can. When was the last time you saw a woman struggling to put on a diaper? I'd like to see that.
