A tabby, dressed in blue, appears to play a tune on a keyboard. Seen on its own, it makes very little sense. But when a YouTube user found the footage and placed it at the end of another video, it spread like wildfire. "Play him off, Keyboard Cat" became a way to signal it was time to wrap it up after an awkward situation or slip-and-fall blooper. Keyboard Cat mashups add a touch more absurdity to already absurd situations, like a man falling off a treadmill or Miss Teen South Carolina flubbing her geography. Combine that with the Internet's penchant for cats, and a craze is born.
