Congress Edits is a Twitter bot that tweets every time a person in US government anonymously edits Wikipedia. This is our favorite edit so far, in which an anonymous person in the House of Representatives added a denial to an article on U.S. politicians being secret alien lizards.
Here's the passage in question, with the Congressional edit in bold:
The idea of reptilians on Earth was popularized by David Icke, a conspiracy theorist who says shape-shifting reptilian people control our world by taking on human form and gaining political power to manipulate our societies. Icke has claimed on multiple occasions that many of the world leaders are, or are possessed by, reptilians ruling the world. These allegations are completely unsubstantiated and have no basis in reality.
Methinks somebody doth protest a bit too much...
UPDATE: Andy Baio notes that this whole thing started with another tweet:
So which charity got the $20? Wikimedia Foundation of course.
