Creepy Trek - Return Of The Archons

One of the creepiest TOS episodes is The Return of The Archons. Kirk's Enterprise encounters a planet ruled over by a super computer who keeps order by projecting a creepy hologram of a long dead ruler - Landru.  The nasty artificial intelligence is assisted by zombie like minions garbed in flowing robes, faces hidden by hoods.  Dunno about you, but I prefer Gru's Minions any day!
