Watching: 2122 The Bob Next Door | Watch The Simpsons Online - FREE!

A financial crisis in Springfield causes the release of all low-level criminals from Springfield Penitentiary and the sale of many houses, including a seemingly mild-mannered man named Walt Warren. Walt purchases a house next door to the Simpson family, and he immediately charms the neighborhood. However, Bart is convinced that Walt is his archenemy, Sideshow Bob, because they have the same voice. Marge convinces him otherwise by taking him to visit the penitentiary, where they see Bob is writing "Bart Will Die!" on the walls. A reassured Bart decides to go to a baseball game with Walt; however, Bart's initial instincts prove right when "Walt" reveals himself as Sideshow Bob. Bob restrains Bart in the car, planning to take him to Five Corners (the location where five states meet) to kill him.
