Yeah, I know, it may be old news for some people here, but there are still probably some who don't know about it.

Uncyclopedia, "the content-free encyclopedia that anyone can edit" is a direct comedic parody on the Wikipedia site. It features humurous articles and satirical topics as well. Very funny reading for anyone that understands it. But just like Wikipedia, it is also subject to vandalism (entering actual factual information, considered one of the most gruesome and inconsiderate gestures possible there).

Try checking out their articles on redundancy, brevity, and recursion. Quite entertaining material, indeed.
