'Nyan Cat' is a recent viral hit, the original video has nearly 2 million views and there's a website dedicated to watching it for as long as possible.

There's a kitten whose body appears to be a Pop-Tart, for no discernible reason. The cat is also excreting rainbows and flying through space, but it's the tasty torso that is most confusing. The music is repetitive and high pitched with the only lyrics being something between 'meow' and 'nyan'. In writing, this sounds at best bizarre and at worst utterly dreadful. But take a look for yourself, and you'll be hooked.
