Wikiality
As many of you know, I love to use Wikipedia to look up random information, obtain knowledge I can then pass on as my own at parties, and cheat at crossword puzzles. Unfortunately, since anyone can post updates to the site, its apocryphal information can be misleading or flat-out wrong. Still, if you're as much a fan of the online encyclopedia as I am, then you have to watch Colbert's take on the site and its ability to bend reality into Wikiality.
