The 'Pickle Rick, Funniest Shit Ever' meme originates from the 'Pickle Rick' episode of the adult animated series Rick and Morty. While the character became a massive marketing icon, the specific 'Funniest Shit' format gained popularity as an ironic retelling of the episode's premise. It usually involves a character—often Joe Swanson from Family Guy or other redraws—describing Rick's transformation into a pickle with exaggerated, breathless enthusiasm. The meme is frequently used to satirize the perceived 'high-IQ' humor of the show's fanbase or to ironically praise a joke that has become oversaturated in internet culture.
