Warning: The following contains SPOILERS for Rick and Morty season 5, episode 2, "Mortyplicty."
Rick and Morty season 5, episode 2, "Mortyplicity" featured a post-credits scene that ranks among the darkest endings in the show's history, running one version of Jerry Smith through a series of perversely humiliating fates. While much of the show's humor aimed at Jerry's expense has been mean-spirited and bitter (much like Rick), in this case it was well-deserved and the post-credits scene ensured that this version of Jerry was justly punished for a disgusting act of cowardice.
The plot of Rick and Morty's "Mortyplicity" centered around a number of robot decoy families, which Rick Sanchez had made to confuse his many enemies and offer him some warning if they ever tried to come after him and his family. It soon became apparent that many of the decoy Ricks had the same idea and had created their own robot decoy families. This resulted in a "an Asimov Cascade Failure," as the various decoys began trying to kill each other, except for one group that tried to form their own underground society living together in peace. Sadly, this group was ultimately killed off thanks to the selfishness of one Jerry Smith decoy, who had a wooden body and resembled an oversized Pinocchio. The post-credits scene detailed the pathetic end of this variant Jerry, as he was torn apart by beavers, made into a mirror, set on fire and ultimately turned into a crucifix.
Rick and Morty manages a careful balancing act in its treatment of the various versions of Jerry Smith. While Jerry is, at his most basic level, absurd and cowardly, he's also a fairly moral man and rarely wrong in his frequent complaints about Rick's amoral behavior. This leaves the show's writers needing to find ways to prevent Jerry from becoming too sympathetic, lest the conga line of indignities he suffers because of Rick's actions stop being funny.
The writers of Rick and Morty addressed this issue in seasons 3 and 4, redeeming Jerry's character and allowing him the chance to win back Beth after a season-long separation. While still remaining the same clueless schlub who had an entire daycare service devoted to taking care of his other-dimensional selves, Jerry became more assertive and began setting firmer boundaries in his dealings with Rick. Naturally he continued to overstep those boundaries with his typical ill-founded confidence, but this just served to drive home that while Jerry had a point about Rick being a selfish jerk, Rick likewise had a point about Jerry's Napoleon complex.
Despite often being the architect of his own problems, it's usually easy for Rick & Morty fans to feel some sympathy for the much-abused Jerry Smith. That's all but impossible in this case, however, and it was quite satisfying to see the Wooden Jerry get his just deserts for condemning so many of his fellow decoys to a painful death for the sake of some varnish. It also helps that Wooden Jerry remained obliviously selfish to the end, declaring that "this is the worst thing that has ever happened to anyone" while talking about himself, even as the alien that has been nailed to him was pelted with tomatoes and jeered by the crowds that came to watch him die.
