Pickle Rick comes from the Rick and Morty episode of the same name, first aired in 2017 during season three. In the story Rick deliberately turns himself into a talking pickle to avoid a family therapy session, then has to fight his way across the city to survive. The episode became one of the show's most quoted, and the shout spread far beyond the series through memes, merchandise and short edits. Its lasting appeal is the contrast between a serious escape adventure and the silliest possible hero.
