I'm talking about a fan theory, that if true doesn't drastically upend the fundamentals of the fiction it is set in.
Mine is that in the American Dad episode 'Can I Be Frank With You', that Snot's uncle is actually just another Roger persona. He appears suddenly and conveniently to pitch a bizarre scheme, he loves hanging around with teen boys and doing drugs, and the very instant that the plan has a setback he kills himself out of sight of everyone else. That's just Roger in a suit and glasses.
Edit: Ok, so, people are having trouble with the word "inconsequential".
The Lion King is an experiment being run by the aliens from Close Encounters of the Third Kind. The music is diegetic and is used to modify behavior.
We know they can implant images and subconscious commands, and that this is perceived through music. That's why they can coordinate musical numbers on the spot, and why sudden changes in behavior and attitude are accompanied by music.
In particular, the most critical character change comes when Simba wanders off to be alone, sees a vision in the sky, and the soundtrack kicks in with an extended version of the alien music from Close Encounters of the Third Kind. Suddenly he's doing a 180 and running back towards his assigned role in the story.
