"I Don't Wanna Know Why the Caged Bird Sings" is the fourth episode of The Simpsons' nineteenth season, and first aired on October 14, 2007. For the second time in the series, Marge helps a prison assailant. Marge meets Dwight (Steve Buscemi), a man who attempts to rob the bank the two are in. Marge promises that she would visit him in prison, should he turn himself in, but too frightened to go into the prison, she breaks her promise. It was written by Dana Gould and directed by Bob Anderson. Steve Buscemi makes his second guest appearance on the show, (originally appearing as himself in "Brake My Wife, Please") though this time he voiced a character, Dwight. Ted Nugent has a voice cameo. Julia Louis-Dreyfus makes a surprise guest return as Snake's girlfriend Gloria, who originally appeared in "A Hunka Hunka Burns in Love". During its first airing, the episode originally garnered 8.8 million viewers, higher than the previous episode.
Homer is smugly waiting for Marge at the ceremony. Marge privately calls Homer, informing him she's a hostage at a bank robbery. Dwight notices Marge on the phone. Dwight makes a compromise; he will promise to turn himself in as long as Marge promises to visit him in prison, to which she reluctantly agrees. A nervous Marge returns home. Homer attempts to convince Marge not to visit Dwight in the prison, but Marge wishes to honor her promise and visit him. However, while going to the prison, she makes continuous stops to avoid going to the prison, and misses visiting hours. At the prison, Dwight expectantly waits for Marge. While watching Snake Jailbird and his girlfriend, Gloria, Dwight becomes depressed and then angry, and Marge's guilt begins to get to her while watching a frightening movie about a prisoner who was to be electrocuted. At the same moment, Dwight is breaking out of Springfield Penitentiary. He finds Marge's address in a newspaper, and sets out to find her.
At home, while watching TV, Kent Brockman makes a news report on Dwight's escape from prison. Dwight begins stalking Marge in various places, and successfully catches up to Marge and keeps her as his hostage. Dwight takes her to the same amusement park where he was abandoned by his mother, with the intention to have Marge help him repay the time he had lost, and promises to let her go afterwards, to which Marge, out of sympathy, agrees. He and Marge then ride the Viking ship ride together. Chief Wiggum arrives attempting to save Marge, but he is caught in the ride. Dwight jams the ride's gears by throwing in his own body to save Wiggum. He survives, fortunately, and returns to prison after being hospitalized and making a full recovery. Back at the prison, Marge finally visits Dwight, who gives her a flattened dandelion encased in a bar of soap he had carved for her with a message on the back intending to recruit her in helping him attempt another prison break. Marge does not agree to the escape attempt and Dwight, although saddened, says she can keep the token.
