This cartoon is a prime example of Tex Avery's brilliance and how producer Fred Quimby could pick'em. Slap Happy Lion show's us how too much confidence can run short to the unlikeliest of foes. Avery delivers gag after gag with the goofiest lion flexing his king of the jungle muscles with roaring laughter. This is truly one of the reasons why I've always been a fan of vintage cartoons from the MGM studios in a time when shorts such as these were seen only at the theater. A true hidden treasure of the Avery archives...8 out of 10.
Slap Happy Lion can also be found appropriately as a special feature on the classic Thin Man series finale "Song of the Thin Man" on DVD.
