Yeah. Rick and Morty is all about sci-fi fantasy going off the rails, and not always for comedic effect. The show embraces its own darkness instead of trying to get as many cheap laughs as possible. What we had here is a dark gag about how literally a machine can take commands, but it's taken to the right amount of far that there's a logic to it. The melting child psychological ploy was one of the darkest things I've seen, but it's done just deviantly brilliant enough that it's both hilarious and horrifying. Something most adult animated shows don't really get. I'd say this does to sci-fi what Venture Bros does to Saturday Morning Cartoons and teen action cartoon teams.
Other adult cartoons are like "how many crude jokes can we get away with in 11 minutes?" Problem with crude jokes is, only younger audiences would even appreciate them because the worst thing about shock humor is, once you're desensitized enough, it just comes off as lazy. It's like, "yeah! [Family Guy and/or South Park] already did that joke 10 years ago." I caught some of that
awful Tosh.) show where they were doing a musical about how gay He-Man was, and all the jokes were just saying how gay the character is. And I'm like, wow... didn't Robot Chicken do that forever ago, and it's
still not as funny as the accidental innuendo in the
actual cartoon?
Turbo Teen! Yes, now that you say it, that totally makes sense given what Ric was spewing to Morty, only to tell him to never mind as a taxi suddenly showed up instead.
What made the joke really pop out wasn't just that it was a passing reference with a "never mind" thrown in, but the stinger at the end of the episode where Morty actually
does turn into a car in the middle of class for no apparent reason. It's a nice reference as a throwaway joke, sure, but following through on it was divine.
