May the Fourth be with you!
If you've been around here a while, you know I love me some Wikipedia, and here's what they have to say about Star Wars Day:
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:
Nikki Doe: You're in!
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 and the Chicagoan Convention is known to occur on this day two years ago.
So go ahead, and spread some Star Wars Cheer and remember...may the Fourth Be With You!
