Honestly. The helmet Bart wears in the EARTHLAND REALMS role-playing game in the Season 18 episode ''MARGE GAMER'' is just like the helmet Rexor wore in the scene from CONAN THE BARBARIAN, where Thulsa Doom and his evil warriors of the Snake Cult slaughter Conan's people and murder Conan's parents.
Seriously. I am not making it up. They've got clips of that episode on YOUTUBE.
