The Substitute Spanish Prisoner is the one hundred-fourteenth episode of King of the Hill. It was first aired on March 3, 2002. The episode was written by Etan Cohen, and directed by Kyounghee Lim and Boohwan Lim.


After handing back tests to her class, Peggy is dumbfounded when Dooley asks her to explain the answer to a question. To restore her self confidence, Peggy takes an internet IQ test and discovers she's a genius. She attends a seminar with other local 'geniuses,' one of whom is Jimmy Wichard which should have told Peggy something, and ends up buying a phony Ph.D. Angered that Peggy has spent their retirement money, Hank explains to her that she is the victim of a scam. Peggy must prove that she is smart by getting the money back, and is inveigled into further dealings with the con man.


The episode title is a pun on the Spanish Prisoner con scheme and Peggy's job as a substitute teacher of Spanish and other subjects.

The con Peggy uses to try to get all their money back is called the Wire Game.
