Perhaps the only animator daring enough to be nuttier than the Looney Tunes was Jay Ward. His George of the Jungle not only lampooned Tarzan, but would've felt right at home airing in primetime, too, as Rocky & His Friends originally did.
In "The Sultan's Pearl", George (Bill Scott) is tasked to locate the titular object, and is led to believe, along with the viewers, that the pearl is just that. But, of course, well........! Paul Frees narrates.
When a Canadian studio acqured the rights to George a few years back, it lacked the subversive, subtle comedy of the original. Like, what a surprise, eh?
