I love Back to the Future. Which is why it uncharacteristically annoys me when I keep seeing people sharing an image of the time circuits with a photoshopped date. Most of them are marginally better than this one.
The actual date that Marty McFly travelled to the year 2015 is October 21.
And oh, by the way, Biff’s 1985 is far superior to any other 1985.
