I can just imagine the Pitch Meeting for Captain Caveman, so many years ago:
"Hey, guys, we really need something new. Something original for our Saturday lineup this year. So what can we rip off, and get away with?"
"Hmm. Well, 'Charlie's Angels' is the hottest thing on tv right now. We could do an animated version of that!"
"A bit racy for the kindergarten set."
"Why not make them teenagers? Everybody knows teenagers don't have sex!"
"Hmm...I don't know. It still sounds like kind of a rip-off. We need something original, here. Something that's not a rip-off, but is a rip-off. You follow me?"
"Well? Why not make one of them black?"
"Hey! That's a great idea! Yeah! And we'll call them the 'Teen Angels' instead of 'Charlie's Angels.' That way, Aaron Spelling can't sue us!"
"Brilliant, but it needs something more."
"I agree. We can't add a mystery-solving dog to the thing. Then we'd be stealing from ourselves...yet again!"
"Ho, ho ho! That is so. But say listen, last night I stayed up and watched this old movie where they thawed out a caveman who'd been frozen in ice..."
"That's it! We'll add a caveman to the show! I think we've got it!"
"Yeah, but a caveman running around in a loincloth...hmm...that's kinda too sexy for Saturday morning, too."
"Well, we'll make him real old. That way nobody will think he's actually having sex with the Teen Angels."
"Hmm...not enough. He'll have to be covered up, I should think."
"Covered up? I know! We'll make him look kind of like Cousin Itt! That'll take all the sex right out of this show!"
"You're a genius! So he'll be a really hairy caveman...exactly like the Slag Bros, NOT Cousin Itt. Right? Because we did NOT rip off the Slag Bros. from Cousin Itt...it was the other way around, right?"
"Right! And...hey, that 'Dynomutt' thing is doing pretty well. So why not make the caveman a superhero, to boot?"
"THIS IS AMAZING! This will be the most FANTASTIC SHOW of our careers! Let's do it!!!"
