Will the real Seymour Skinner please stand up? A man named Seymour Skinner shows up in Springfield claiming that the man who works as Springfield Elementary School's Principal is an imposter. It turns out that the Skinner who's lived in Springfield all these years is really named Armin Tamzarian, and met the real Seymour Skinner in Vietnam. The real Skinner was a highly decorated Sergeant, while Tamzarian was a fifties-style greaser and juvenile delinquent. The real Skinner was captured by the enemy, held in a POW camp for five years and then sold to China as a slave forced to make sneakers in Wuhan. Tamzarian stole his name and identity, moved to springfield and took over Skinner's former life, even claiming the man's mother, Agnes, to be his own. With the real Skinner back, the fake Skinner quits his job at the school, moves out of his mother's house and starts a new life as a loser in Capital City. Meanwhile, the real Skinner takes over at Springfield Elementary School and proves to be much less bearable than the old Skinner. In desperation, Agnes Skinner, Mrs. Krabappel and the Simpsons travel to Capital City to beg Tamzarian to come back. With Tamzarian's return, Sergeant Skinner is banished from town and everyone agrees to accept Tamzarian back as Principal Seymour Skinner.
