Ashamed that I know this, but yeah the episode had something to do with like zombies or something... and the mayor guy was playing... I don't remember the name of the episodes, but I think it was an early one cuz this is going way back when I was little. Used to freak me out cuz the zombie things.. or whatever was in there... oh yeah also had something to do with like an evil magician guy that killed people... really creepy. But I remember that being my favorite episode as a kid cuz of the Zelda reference. Hope that helps?
Oddly enough, that is the one scene that I actually remember in that show.
I believe this is the scene you refer to (though I don't remember the exact episode): http://www.youtube.com/watch?v=ywqlYujA0zQ
And now that I watch it, it has great irony.
