High Quality Content by WIKIPEDIA articles! "Radioactive Man" is the second episode of The Simpsons` seventh season. It originally aired on the Fox network in the United States on September 24, 1995. The episode sees the film version of the comic book series Radioactive Man set up production in Springfield. Much to Bart`s disappointment, the part of the hero`s sidekick, Fallout Boy, goes not to him, but to Milhouse. Milhouse, however, hates acting, so he quits the role and leaves the set, forcing the producers of the film to shut down production and go back to Hollywood.
