The video is a humorous and iconic internet meme featuring a cat named "Fatso" wearing a tuxedo and "playing" a keyboard. The cat's actions are not coordinated or musical in any way, but the humorous juxtaposition of a cat in a tuxedo with the music creates the comedic effect.
The video was created in 1984 by Charlie Schmidt and his friend Benny. The music is the song "The Ballad of the Green Berets" by Staff Sergeant Barry Sadler.
While Keyboard Cat isn't playing music, the meme has become a beloved symbol of internet humor and a testament to the power of unexpected and funny videos.
