WKeyboard Cat is a video-based internet meme. Its original form was a video originally made in 1984 by Charlie Schmidt of his cat Fatso seemingly playing a musical keyboard to a cheery tune. While Schmidt had uploaded the video himself to YouTube in 2007, Brad O'Farrell, with Schmidt's permission, appended the video to the end of a blooper video uploaded in 2009 as if to have the cat "play" the person offstage after the gaffe as they had done in Vaudeville. The idea of this quickly expanded on the Internet by numerous other users, typically under the name "Play Him Off, Keyboard Cat", and became a meme.
