Nyan Cat is a looping video depicting a cartoon cat with a poptart attached to his back and flying through space while singing a repetitive "NYAN NYAN NYAN" sound and leaving a rainbow trail.

The video became a viral internet meme in YouTube.

ORIGIN:
The origin of such meme it's believed to be in the "Buttered Cat Paradox" which states that a buttered bread will allways land buttered side down and a cat will allways land on their feet, so attaching a buttered bread (or a poptart) on a cat's back will cause an anti-gravity effect making the cat to float indefinitly. (This doesn't explain the NYAN NYAN sound, but I believe that was added to the video just to make it cute... and annoying)
- What would happen if I tie a buttered bread to a cat's back?
- You'd get a Buttered Cat Paradox!! just like the Nyan Cat

The day the Nyan Cat crashed into the Twin Towers.

Contrary to popular belief, the destruction of the Twin Towers was caused by terrorists. This is incorrect.

This was merely Nyan Cat's orbit into Earth's atmosphere on it's quest to Nyan across the galaxy.
"Now class, today we will reflect briefly on 9/11, a day terrorists killed hundreds of Americans by the destruction of the Twin Towers."
