Take a second to go down memory lane by perusing the Wikipedia entry for "Land of the Lost"

This series scared the crap out of me when I was six. Those Sleestaks were damned creepy and the Tyrannasaur would make me jump. Yet I couldn't stop watching it, I guess because of the sense of mystery and curiosity of what, exactly, was going on. It's funny how I remembered things about the series only as I read about them (time pyramids, control centers, lost cities, etc.) Sort of like going through an old junk drawer and finding stuff you never even realized you'd lost.
