Klasky-Csupo, Inc. (pronounced "Class-key Chuppo") is a multimedia entertainment production company located in Los Angeles, California, founded by artist/producer Arlene Klasky and master animator Gábor Csupó.
Klasky-Csupo did the animation for the The Simpsons Ullman shorts and the first three seasons of the series, until the animation was taken by Film Roman, Inc. The company had an argument with the executives of the show about "Some Enchanted Evening", the episode that was originally going to be the first one, but was left as the first season finale, since the animation was not good for the producers.
