This is another one of those little clips on YouTube that seems to have a life of it's own. It is everywhere!!! This guy made a short film of his cat 'playing a keyboard' (less than a min.) And people have re-used it and now it's an internet meme (a catchphrase or concept that spreads quickly from person to person via the Internet)!
Here is the "official" description from the "Keyboard Cat" Wikipedia page!
"Keyboard Cat is an internet meme. It consists of footage of "Fatso", a cat (now deceased) owned by Charlie Schmidt of Spokane, Washington, "playing" an upbeat rhythm on a electronic keyboard. The clip has gained popularity by being appended to blooper and other viral videos as if to "play" that person offstage after the mistake or gaff, usually accompanied with the title Play Him Off, Keyboard Cat or a variant. The first such video was created by Brad O'Farrell. Keyboard Cat was further popularized by Stephen Colbert on May 18, 2009, during a "toss" with The Daily Show with Jon Stewart."
Here is the orginial:
I can't list them all, but here are just a few of the ways in which it's being re-used as the best clip ever!!
The band Green Day got in on the action!
And my personal favorite!
