Perhaps o.o Shrek and a lot of other dreamworks were incredibly crude humored, and some pixar films too. Actually, I think you're right, as it stands I can't think of any crude humor besides those supposed "subliminal messages" in the movies, that even if they are there, no one really notices them, and they were probably added in their by some young animator that wanted to add a little something to it that only he would see, like how Wesker does some small little things in a few of his Marv comics that no one really notices, but he knows they are there.
=/ Maybe that was a false accusation, but a lot of the real life actors and movies based off them I'm noticing a little bit of crude humor, but like I said, these movies are crap anyway. The 2D animation is definitely better.
