56 Episodes of Star Trek: TOS At Once

Below is a video that gives you the opportunity to watch all of the first two seasons of Star Trek: The Original Series at once. At least in theory since after the initial theme music it becomes a bit of a noisy mess. The initial series pilot episode, The Cage, isn't part of the grid but then again it didn't air as part of the first season anyway as most of the cast was replaced with the now famous crew with the reproduced pilot episode of Where No Man Has Gone Before. The result is fascinating and best watched in full screen.
