I finally purchased my favourite episode of Mystery Science Theatre on DVD.  I stumbled across the Zombie Nightmare VHS back in high school at the old Video 99 on Bridgeport, down the street from The Dollhouse.  That was my first introduction to the mighty Thor.  This movie is so fun and bad, so I knew the MST3K episode must rule, and it does.  Probably the funniest one if you ask me.
