It either takes a brave soul or obsessed fan to watch The Star Wars Holiday Special, even on May the 4th.
For those unaware of it's existence, it was a variety show aired on TV in 1978, built around the success of the original Star Wars film. 
The story (ha ha) sees Han Solo & Chewbecca try to get back to Chewie's home planet to celebrate Life Day with his family. Various celebrities like Bea Arthur and Jefferson Airplane also share the joy with some terrible songs.
The overall result was so poor that it was only shown on TV once, and with George Lucas spending 38 years trying to destroy every copy, the only hope of viewing it is via a bootleg copy or on YouTube.
Harrison Ford claims to have never watched it, nor does he ever intend to. Carrie Fisher, however, gleefully admits that she shows it whenever she has a house party, but only to prompt guests into leaving.
For those who claim The Phantom Menace is the worst Star Wars film, you're wrong. The SW Holiday Special is far, far worse.
