1) The late, great Steve Ihnat as Lord Garth - Over-the-top doesn't begin to describe his performance! Love the little changes in his voice, from high-pitched adolescent, to lo-voiced psycho. "Si-lience!"
The way his voice goes up at the end of his "I should kill you with my BARE HANDS!!!" is pretty hilarious. Seriously, it's quite an accomplishment to overact more than Williams Shatner.
