It will only ever happen once in the entire history of mankind! It is… (drum roll please) Back to the Future Day!

For those who are unaware of the significance of Back to the Future Day, it is the day (October 21, 2015) that Marty McFly and “Doc” Brown travel to in the second part of the movie trilogy. In an attempt to save Marty’s future son from the trouble he causes in 2015.

“The irony of this movie about time is that it is timeless.” –Michael J. Fox

It was a day that has been awaited since the movie’s 1989 release, and while there are a lot of unrealistic predictions about life in 2015, there are many things that the writers got right or were at least close.

While there may not be a Jaws 19, hologram billboards, or self-adjusting clothing, there are designs for hover boards and flying cars. Also we have flat screen TVs, video chatting through cell phones, and kids are preoccupied with latest digital devices.  Even though they may not be super high tech glasses, google has come out with their product “google glass.”

In the movie they also guess that the Chicago Cubs will win the World Series, and while they may not win, they do have a 12.5% chance of winning the series this fall.

If you have been living in your basement for your entire life and have no clue what Back to the Future is and have no idea how to celebrate this glorious day in history, here is how. You can get yourself a big bucket of popcorn and watch the entire trilogy, see if your local movie theater is playing the second film, or jam out the classic melody only known as “The Power of Love” by Huey Lewis and the News (the theme song to the movies).
