I hate that I’m writing this because I’m gonna sound like the *"to be fair * copy pasta but, the fact that it’s so lame and stupid is kind of the whole point of the bit.
He gives his big “I’m pickle Riiiiick!” presentation like it’s supposed to be some big huge awesome thing, and it’s presented like a punchline that you’re supposed to laugh at and find funny… Then it’s a hard cut to Morty’s disappointed, slightly concerned face for a solid 10 seconds. Morty is you, the viewer, painfully unimpressed by what is presented as, well, “the funniest shit ever”.
Remember in an earlier episode when Rick makes a reference to the non-existent Redgren Grumblholdt, and the kids laugh because they think it’s supposed to be funny and just want to fit in? Those are the people that the “funniest shit ever” meme is about. People that are fed an intentionally bad joke, don’t understand the irony behind the bad joke, but sees that everyone else is laughing at the bad joke, so they pretend the joke is funny. Two people laughing at the same thing for entirely different reasons.
The whole Pickle Rick plotline is just background events anyways. The meat and potatoes of the episode is with Dr Wong.
I don’t have an exact answer for your question, but I will say that when it comes to shows like these you have to remember that they’re very much TV shows and are heavily edited to present a specific narrative. I’m not saying that’s necessarily bad or nefarious, but you just have to take the events and the way in which they happen with a large serving of salt.
A family member was approached by their team (Holme’s) to do the cabinets for a home that was being redone in our area. They literally wanted to pay him in exposure. I wouldn’t be surprised if that’s how a majority of their contracts work; hire a bunch of people to do the actual labor, tell them their payment is in advertising, then stand in front of the camera the whole time and take all the credit when the family shows up.
