Thought this was interesting: May 4 is called Star Wars Day because of a pun or play on words based on the similarity between "May the 4th be with you" and "May the force be with you", a phrase often spoken in the Star Wars movies. In common usage the joke might be presented: John Doe: Happy Star Wars Day! Jane Doe: What? John Doe: May the 4th be with you! As an example of the cultural impact of Star Wars, the joke is recorded in the UK parliament's Hansard. Loyal fans of Star Wars, on this day, participate in a variety of activities. Movie Marathons are common whether or not this is a weekend.
