On the other hand, "You could make a banana purple," he said. "You can put three hats on a cowboy. That would require several days of stitching in live action that you wouldn't be able to afford."
But animation has its advantages.
"We're able to create any sort of the insane alternate dimension ," said Justin Roiland, co-creator and executive producer of "Rick and Morty" — a decidedly offbeat series.
Rick (voiced by Roiland) is a nerdy guy who's none too adventurous. His grandfather, Morty (also voiced by Roiland), is a drunken mad scientist who drags Ricky into adventures he's not prepared for.
In the premiere, Morty drags Rick into another dimension.
It's weird. It's wacky. It's meant for adults — it is part of Adult Swim, after all.
And "Rick and Morty" is often funny, sometimes hilarious.
Harmon is best known for "Community," a show with a small but rabid following. And he made headlines when Sony and NBC fired him from the show he created after the third season, then rehired him for the fifth season, which begins airing on Jan. 2. That is, well, sort of weird. Even for Hollywood.
"He's a talented, genius writer, who writes some of the best dialogue that I've ever read," Roiland said. "And I think that's more important to Hollywood than anything else."
Well, not necessarily.
But Harmon, who's notoriously unhappy much of the time, seems happy working for Cartoon Network. He called Mike Lazzo, the executive vice president/creative director of Adult Swim, "a bona fide genius" who has "the mental power to actually take a script ... read it and then tell you what his reactions were."
"He never says, 'I don't think people are going to like this.' He never branches out into the business of speculating about this biomass for which we are creating it," Harmon said. "And he also never confuses the script for the finished product."
You sort of get the idea Harmon doesn't care for the execs at NBC and Sony, don't you?
