after them when the concept of a third dimension is brought up. In David Foster Wallace's novel Infinite Jest (1996), it is briefly mentioned that students from the Enfield Tennis Academy could be seen studying and highlighting copies of Flatland on the bus. Flatland features in The Big Bang Theory episode "The Psychic Vortex", when Sheldon Cooper declares it one of his favourite imaginary places to visit. On the series The Orville, episode "New Dimensions", after entering a region of two-dimensional space Captain Ed Mercer references Flatland and its theme of social hierarchy. In the Sons of Anarchy episode "Straw", Clay Morrow is lounging on a cot in a private cell in county jail when he first meets retired U.S. Marshal Lee Toric. Morrow half-ignores Toric while keeping his eyes on a copy of Flatland. In Gravity Falls it is implied by the main antagonist Bill Cipher that he originates from a dimension very similar to Flatland.
