Go to YouTube and watch a video, good times! They’ve got a link to take it out of April Fool’s mode. I think you may also be able to get the same effect at any time if you add “&flip=1″ after the address of any YouTube video. Awesome, I love April Fool’s Day online. I’ll try to update with more sites as I find them.
Update: This only worked on April 1, 2009.
