The name "Chewbacca defense" comes from "Chef Aid", an episode of the American animated series "South Park". The episode, which premiered on October 7, 1998, satirizes the O. J. Simpson murder trial, particularly attorney Johnnie Cochran's closing argument for the defense. In the episode, Cochran bases his argument on a false premise about the 1983 film "Return of the Jedi". He asks the jury why a Wookiee like Chewbacca would want to live on Endor with the much smaller Ewoks when "it does not make sense". He argues that if Chewbacca living on Endor does not make sense—and if even mentioning Chewbacca in the case does not make sense—then the jury must acquit.
