#MayTheFourthBeWithYou: 'Star Wars' fans celebrate unofficial holiday

It's that time again.

May 4 is unofficially known as "Star Wars Day" in honor of the pun-tastic phrase, "May the fourth be with you."

Naturally, fans flocked to social media to pay tribute to the popular films, this year paying special attention to Princess Leia actress Carrie Fisher, who died last year.
