Monster A-Go Go (1993)
Episode of Mystery Science Theater 3000
The crew muses about a wacky short involving the Toronto Skating Club in Circus on Ice (1954). Then the guys watch Monster a Go-Go (1965) where a radiated astronaut has returned to Earth as a giant mutant. It's a battle of the action figures in the invention exchange when the Mads introduce Johnny Longtorso while Joel presents non-violent action figures.
