It's the matchup featured in the sports book that sends Marty McFly on another time-traveling adventure. And it happened for real... sort of.
In "Back to the Future, Part II," Marty travels to the year 2015, 30 years in the future, with Doc Emmett Brown. There, he learns the Cubs won the World Series in 2015, beating Miami, which at the time, didn't have a baseball team. When Biff gets his hands on the sports book, it sends Marty back to 1955 to get the book back and save his family... again.

Well, the Cubs actually took on the Miami Marlins July 4th weekend and won that series 2-1.

Many see it as a good omen. And now, with one playoff win under their belts (the first in 12 years), the "future" seems an almost-reachable reality.
If the Cubs win the WS I wouldn't even be mad because that means MOVIES ARE REAL. #wheresmyhoverboard— Kara Romonosky (@careuhwithaK) October 8, 2015
Forget the fact that the then-Florida Marlins ended the Cubs' last playoff run, the 2003 NL Championship series that included the infamous Bartman catch, the more positive signs we have, the better!
Cubs beat Pirates. "Back To The Future" had a banner: "Congrats Chicago Cubs - 2015 World Series Champs". Zemeckis = psychic?— Michael Eddy (@MichaelEddy6) October 8, 2015
The Cubs, however, weren't playing ball.
"As you can imagine, we've seen a lot of creative chatter on the "Back to the Future" prediction. It's a fun story, but we're content leaving this one for our fans and friends in the media to have fun with for now," the Chicago team told ABC7 way back in April.
I'm all for the jays, but if Cubs win the World Series? Back to the future, baby.— Kyle MacInnes (@soMuchEdge) October 8, 2015
In back to the future 2 the Cubs won the world series in 2015... if they win this year life is rigged— cuppy (@nickcuppy45) October 8, 2015
Considering both teams play in the National League, it would be impossible for them to actually meet in the World Series. And they didn't meet up again this season.
For their part, the Marlins had fun with the coincidence through the season:
Very clever! Marlins have fun with 2015 World Series Cubs over Miami prophecy in 'Back to the Future Part II' http://t.co/J03FSa5uaS— Steven Clenney (@StevenClenney) June 3, 2015
ESPN reports the Marlins took advantage of their famous place in "Back to the Future" lore with a #RewriteTheFuture marketing campaign, and will even donate a portion of the proceeds to the Michael J. Fox Foundation for Parkinson's Research.
