On Oct. 21, 2015, we experienced "Back to the Future Day," which was the date to which Marty Mcfly traveled in Back to the Future Part II. We hadn't yet developed hoverboards or self-tying shoelaces, but pop culture fans still had a lot of fun looking at what the movie got right and wrong about the future (now that it was the present).

One prediction came shockingly close: That the Chicago Cubs would win the World Series ... in 2015.

They were almost there. The Cubs got close to competing in the World Series that year, and they just won the championship this year. Something that seemed utterly ridiculous to 1985 Marty McFly is now a reality 31 years later.

But 2015 is not 2016, so Back to the Future Part II's prediction is still wrong. Close only counts in horseshoes and hand grenades.

You know who was right, though? The writers of Parks and Recreation.

Now, to be fair, that episode of the hit sitcom only aired two years ago. Much less impressive than if Back to the Future had nailed it decades ahead of time. But the Cubs were still not seen as a championship team at the time, having lost 89 of their games in 2014 and 96 games in 2013.

According to The Washington Post, Parks and Rec co-creator Michael Schur is "a lifelong baseball fan and avid Boston Red Sox supporter" who followed the Cubs' minor league progress closely. He made the World Series prediction that you see in the episode "Ron and Jammy," which aired in early 2015. The episode is a flash-forward to 2017, and during a trip to Chicago, some of our beloved characters find the city awash with happiness due to the Cubs' recent World Series win.

You know what this means: Leslie Knope for president in 2048.
