Just watched this Tex Avery cartoon on YouTube in which we see a lion in a wheelchair seeming a little docile. When he and the one pushing him pass a mouse, that mouse tells his story in flashback of when that lion used to roar real loud in the jungle and scare every animal. Then this same mouse came along...Boy, the way Avery milks all those scare gags, one after another, with constant visual expressions that go in places that made him one of the wildest of the animators during the wildest of cartoon decades: the '40s. Describing it truly won't do it justice, you just have to watch this thing like you would any Tex Avery of this period. So on that note, I highly recommend Slap Happy Lion.
