Have you heard of Iggy and the Keyboard Cat ?

Keyboard Cat is an Internet meme. It consists of footage from 1984 of "Fatso", a cat (now deceased) owned by Charlie Schmidt of Spokane, Washington, wearing a blue shirt and "playing" an upbeat rhythm on an electronic keyboard, in reality being manipulated like a puppet by Schmidt. The clip, originally posted to YouTube as "Charlie Schmidt's 'cool cat'", has gained popularity by being appended to blooper and other viral videos as if to "play" that person offstage after the mistake or gaffe in a similar manner as getting the hook in the days of vaudeville, usually accompanied with the title Play Him Off, Keyboard Cat or a variant. The first such video was created by Brad O'Farrell, who secured Schmidt's permission to use the footage. Over four thousand such videos now exist, with a website playhimoffkeyboardcat.com created to collect such videos.  Source: Wiki
