\"\" The Nyan Cat video was temporarily removed from YouTube due to a false copyright complaint.

The video was taken down on June 27th because YouTube thought the meme’s creator, PRGuitarMan, had filed a complaint. However, he has repeated stated on his website that this is not true and has managed to get the video reposted. But do you want to know the real tragedy in all this? (other than people not being able to watch the video for a couple of days...). The tiny Nyan Cat on the video’s progress bar no longer exists!!
