"Extra Large Medium" is the 12th episode of the eighth season of the animated comedy series Family Guy. Directed by John Holmquist and written by Steve Callaghan, the episode originally aired on Fox in the United States on February 14, 2010. In "Extra Large Medium", Peter discovers that he has supposedly developed "extrasensory perception" (ESP) after his two sons, Chris and Stewie, go missing during a family hike in the woods. Soon after being rescued, Chris decides to ask out a classmate at his school, named Ellen, who has Down syndrome, and eventually takes her on a romantic date, which he goes on to regret. Meanwhile, Peter begins performing psychic readings, but is eventually discovered to be faking his ability once he is approached by the town's police force.
