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.
