I saw Infinite Gangnam Style on Boing Boing a couple of days ago and it was something pretty goofy. You can turn it on and it will play the song forever. It chops the song up and jumps around in the song to create a never ending song. Unfortunately only Chrome and Safari play it. I already had Chrome. I needed it for the LEGO Brick building site and it worked on Pottermore before I got Internet Explorer 9.
On YouTube while playing the regular length Gangnam Style I found this parody . It pretty much made me laugh all the way through.
