It's no secret that there are a ton of ridiculously smart Rick and Morty jokes - the whole show is basically about a man so brilliant he's virtually an omniscient god. What's even more impressive than the scientific principles they totally nail is their ability to make such things funny. Of course, not all the Rick and Morty jokes that went over your head are based on obscure scientific theories, even something as simple as a dog named Snowball is actually a clever literary reference. Like The Simpsons before them, Rick and Morty has some of the smartest jokes on television.
While referential humor isn't brilliant and hilarious of its own accord, Rick and Morty has an impressive track record of making such jokes just that. In fact, their referential humor is so complex it occasionally spawns fan theories.
While no one's accusing Rick and Morty of being feminist, there's just something about Latin that makes it inherently intellectual (at least on a superficial level). So in "Raising Gazorpazorp," in which the stairs of the exclusively female society read, "Sis Sempur Calumnium," Latin for "You're Always Wrong," it is a joke that is both brilliant and a touch misogynistic. Plus, it's hilarious.
Jerry's robe, which he wears in numerous episodes, features the Chinese character ruò, which roughly translates to "weak." Jerry's weakness of character is one of the greatest obstacles in his marriage, especially coupled with Beth's domineering nature, resulting in an unhealthy dynamic of co-dependence between the two.
What's so brilliant about this Jerry jibe is that the robe itself with its Chinese character is symbolic enough, representing Jerry's pathological need to look cool, regardless of whether or not he understands the contract he's entering into.
In "Something Ricked This Way Comes," Summer and Rick team up to get super buff and beat the living Hell out of Summer's former employer, Satan. They take the time to beat up a few other folks who deserve an ass-whooping, like a homophobic protestor holding up the sign "God Hates F*gs."
For a frame, the sign changes to "God Hates You." The sign changes just as the hateful protester sees a swole Summer heading in his direction. There are a fair amount of God jokes in Rick and Morty - most of which paint religion in a negative light. Harmon and co. point out that if a god exists, he hates the people who holds up those signs.
Chalk this one up in the meta-humor category. Dan Harmon's production company, Harmonious Claptrap, used to depict claymation versions of Harmon and his wife watching TV, lovingly snuggled up on the couch after every episode.
However, after his real life divorce, the image changed in time for Season 3, now depicting a slovenly Harmon apparently passed out drunk on the couch surrounded by trash with no wife in sight. While this is quite depressing, it's also brilliant, as few would think to sneak humor into an element of the show that really exists outside the show.
