It seems just like yesterday when The Tracey Ullman Show (1987) had this short cartoon segment on it that eventually became its own full fledged show on the Fox Network. The animation was crude but the writing was anything but. That was 30 years ago. When The Simpsons (1989) was greenlit, that crude 2D animation became top notch. This new show also garnered a loyal following of fans along with a surprising number of Hollywood's top stars too. Over the past 30 years many of those top stars have guested on the show that has been renewed up to season 32. Who is your favorite Guest Toon? After voting, please discuss here.
