Rick and Morty is at once brilliant and moronic, totally brand new yet somehow really familiar, and even though the show has moved far away from creator Justin Roiland's original concept that has proven to be a good thing. So what, you may ask, was Justin's original concept?
The Real Animated Adventures of Doc and Mharti, which was meant to troll Universal Pictures and "poke fun at the idea of getting cease and desist letters", original title Back to the Future: The New Official Universal Studios Cartoon Featuring the New Doc Brown and Marty McFly. (NSFW)
As you'd imagine the short is raunchy and very NSFW, but it also serves as a great example of how a concept, however crude, can become something great if you selectively breed that concept into a champion.
