Crude animations.

Have you noticed. Almost every time you see a promo for a kids' film, even Disney films, it will include a scene that is particularly vulgar.  The movie itself will, of course, have lots of toilet jokes.
I won't list the subjects they choose, suffice it to say they are all scatological. Apparently someone told filmmakers that children find any kind of toilet humor hilarious, which may or may not be true. They only thing I'm sure of is thanks to today's filmmakers, we are pretty guaranteed of having a generation of boorish adults who adore bathroom humor.
