“The Blunder Years” is the fifth episode of Season 13. It originally aired on December 9th, 2001. The episode was written by Ian Maxtone-Graham and directed by Steven Dean Moore. Paul Newman, Joe Mantegna and Judith Owen guest starred. The episode title is a play on the television show, The Wonder Years, while Homer’s flashbacks are parodies of the movie, Stand By Me.
A restaurant hypnotist causes Homer to relive a traumatic childhood experience where, upon swimming in a quarry, he found a dead body. That dead body turned out to be Waylon Smithers’ father, Waylon Smithers Sr., who had disappeared twenty-five years earlier under suspicious circumstances. Meanwhile, Marge fancies Chad Sexington, the man who appears on the packaging of Burly paper towels.
