A fake plastic-surgeryed Superman ("Houdini" Watson) convinces Jimmy he's temporarily transferred his super-powers to Jimmy - and that Superman must hide from Clark Kent, who plots to kill him with kryptonite for a mob reward! The scheme is to get Jimmy to retrieve a list of "dead" criminals with new plastic-surgery faces from Clark's desk. There's a kryptonite-laced cake, a runaway train, a kidnapping at gunpoint - and Jimmy falls for the entire triple-hoax, because even the kryptonite is fake!
