"Minuscule," a series of some 75 computer animation shorts, has some great writing and sound design -- but, better yet, they are really funny.
The Cartoon Brew blog has the story of who's behind it, along with some clips. This is a French production, and it's being distributed on TV by Disney. Each clip is a whole episode; about 3-5 minutes apiece.
I laughed out loud at a lot of these.
