Various sci-fi projects have attempted to answer "What's the meaning of life?" While "The Hitchhiker's Guide to the Galaxy" has famously labeled the answer as "42," "Rick and Morty" has suggested on numerous occasions that ice cream is what holds the universe together and makes the world go round.

The theory first gained traction within the fan community when Tumblr user awholecroissant began to ruminate on what connects each episode. Leaning into the meta nature of the series, the user suggested that a thread exists between the use and importance of ice cream throughout the show. Ice cream first showed up in the third episode of the first season, "Anatomy Park." In the episode, Rick sends Morty into the body of his friend, Reuben, to save his life. Inside, Morty discovers that his irreverent grandfather has created a "Jurassic Park"-like theme park inside Reuben's body.

Things naturally go wrong for the colorful cast of characters, and as the body itself faces death, an amoeba inside Reuben, Dr. Xenon Bloom, begins to binge eat ice cream as it's what "true happiness and pleasure" is for him in his final moments. This sets the stage for the rest of the delicious theory.
