Super President: The President and the Pirate (1967)
Super President was a cartoon that aired Saturday mornings on NBC from September 16, 1967 to December 28, 1968. The series was produced by the DePatie-Freleng animation company. If there is a hell for animators DePatie and Freleng are standing there with surprised looks on their faces. These dudes were to animation what the Westboro Baptist Church is to Christianity (who will also one day be standing in Hell with surprised looks on their faces.) Animation Hell is a lot nicer than than regular Hell--animation Hell is just a place bad animators go when they die to watch bad cartoons for all eternity.
