Anyone who helped to bring the world "The Simpsons" should be celebrated. Huge talent, loved to play poker. At the end he was rapidly giving away his fortune.
He was married to a YOUNG Jennifer Tilly, so, yeah, while he only alive 59 years, he had a great life. RIP.
Some pics of a young Jennifer Tilly from "Let It Ride" (when she was married to Simon) and then a later career pic after she got a little enhancement.
