If you spent a millisecond online yesterday or just happened to take your DeLorean out for a drive, then you probably know yesterday was Back to the Future Day. Something, something hoverboards!

To jump on the 80s nostalgia wave, Michael J. Fox and Christopher Lloyd went into full Back to the Future Mode and made an appearance on Jimmy Kimmel Live last night as their characters from the movie. 

Doc and Marty quizzed Jimmy on all the things that didn't happen in 2015 like flying cars and hoverboards, but on the plus side we can now watch TV on our phones while sitting on the toilet!

The downside of course is that real-life Biff is now running for president.
