The hottest new meme on the Internet is Nyan Cat, a rainbow-riding animated cat with the body of a Pop-Tart. Nyan Cat amassed millions of views on YouTube after a user set a LOL-COMICS .gif to an annoying Japanese song. The idiocy of Nyan Cat makes us wonder: just how are these Internet memes thought up in the first place? Though it may seem so to young Internet users, Nyan Cat is nothing new. The equally-annoying Hamster Dance was a staple of the '90s.
