Japanese animators, I believe, choose to spend much of the money and resources they have to work on a series on making the art very complex -- for example, a lot of times a character running will really just be jerking back and forth yet in another scene they will have meticulously animated the same character's hair blowing dramatically in the wind.
Compare:
Anime sacrifices fluidity, and, sometimes, actual motion in its animation for complexity (except when it has an overload of super-deformed scenes.... then it sacrifices both). Dramatic panning, yay!
.....also, I know we've been over the "toilet humor" thing but I just went into the kitchen and B&M was on TV and the first thing I heard was "I dare you to sniff your own butt."
.....yeah.
