Great Scott! Is it already Back to the Future Day, the day Marty McFly and Doc Brown drove their time-traveling DeLorean to 2015 to see old Marty get fired by Flea? How time flies.

Yup, it's one of the internet's favorite fan-driven holidays, a day to kick back, relax and realize that we're still tieing our shoes like suckers. It's been five years since October 21st, and we still don't have real Hoverboards, sleeve-shortening jackets or "Jaws 19."

What we do have are Back to the Future memes. And while there have been numerous hoaxes about Back to the Future Day, there's actually only one. According to october212015.com, today's the day. So happy Back to the Future Day and sip a cool Pepsi Perfect and enjoy the memes.
