Star Trek - Return of the Archons. Kirk and company find themselves on a planet where the populace are happy and content. All the time. Except when they're crazy. Really liked this one, very creepy. The vacuous "happiness" of the people reminded me of the Jasmine story arc in season 4 of Angel and just as unsettling. Kinda digging TOS these days, always had trouble getting into it before but it's winning me over now.
