The big surprise at the party honoring Seymour Skinner's 20 years as principal is that the real Seymour Skinner shows up. He has just returned to the US after being held as a POW for 26 years. Our Skinner's real name is Armin Tanzarian, who used to be a real hell raiser in his youth. He met Seymour while serving under him in Vietnam. Feeling rejected, Armand resigns as principal and hits the road. The town tries to get used to the real Seymour Skinner, but can they? The real Seymour is a weenie. Edna and Agnes begin to miss their old Skinner; meanwhile, the impostor Skinner is in a nearby town, advertising a for a strip club. Marge, Edna, and Agnes get together and form a plan to bring him back. They travel to meet him and he claims to be a changed man. He has a seedy apartment and a subscription to "Swank." They convince him to return and then the town gets rid of the real Skinner and Judge Snyder orders that they never to discuss him again and everything is back to normal.
