Rick and Morty is an American adult animated science-fiction sitcom created by Justin Roiland and Dan Harmon that premiered on Adult Swim in 2013. It follows brilliant but reckless scientist Rick Sanchez and his anxious grandson Morty Smith on dangerous adventures across dimensions and alien worlds. Short clips from the show spread widely through YouTube, TikTok and meme pages, where fans reuse its dialogue, theme and chaotic energy in edits and reaction videos. It remains popular because its blend of dark humour, science-fiction ideas and instantly recognisable characters translates easily to short-form comedy.
