"Radioactive Man"
Season 7, Episode 2

When the filming of Radioactive Man moves to Springfield and castings begin for a local kid to play Fallout Boy, Bart is absolutely set on playing the part. He's told he'd be perfect for the role...if he wasn't exactly one inch too short. So he employs every style trick in the book to appear taller. A vertically striped suit, platform kicks, extra tall hair, and a tiny dog are all for naught, but Bart's sweet mod look (minus the dog) would work anywhere else.
