May the Fourth be with you! — Today is the unofficial "holiday" dedicated to George Lucas' galaxy far, far away.

History says the pun was first used in 1979, with Britain's Conservative Party congratulating Margaret Thatcher in print for taking the prime minister post that day.

According to Canada's Globe and Mail newspaper, the first organized "Star Wars" event on May 4 took place in 2011 at the Toronto Underground Cinema.

As you can tell, it's picked up a lot of steam since then. So much so, businesses have gotten on board to help you (help them) enjoy the special celebration.
