The Simpsons reference you missed in Rick and Morty’s Vat of Acid episode
From the end of the episode, it turns out that Morty’s device doesn’t work at all how he planned, and Rick actually devised the little gadget to be an elaborate and devastating lesson for his mouthy grandson. The lesson to the audience, of course, is don’t blink if you don’t would like to miss one of Harmon’s clever references on Rick and Morty.
In the beginning, Morty uses the save device to fulfill his darkest inclinations. In one interaction, he comes upon an old guy sitting with a crosswalk in a wheelchair. Morty pretends to offer his assistance, and instead dumps the poor old man unceremoniously. After undoing this act of unspeakable cruelty with his handy-dandy device, he makes the guy across the street. You missed that pub in the background, which is a dead ringer for Moe’s, In the event you were focused too closely on the interaction between the guy and Morty.
It makes sense that Harmon would opt to use this Springfield watering hole that is small to honor his predecessor in the sphere of animation. Locations in television history are as iconic as Moe’s Tavern. There is the Seinfeld diner and the coffee shop from Friends, of course. Moe’s Tavern occupies atmosphere.
