The single greatest, most side-splittingly hilarious case of overacting in acting history. Throw it into any serious moment and people will piss themselves laughing. Particularly when they are baked, but that goes without saying with Stoned Star Trek.
Star Trek II was good but overrated IMO. The best Star Trek movie of all times is VI: The Undiscovered Country
