Marty McFly and Dr. Emmett Brown visited Jimmy Kimmel Live! on Wednesday night. Actually, Michael J. Fox and Christopher Lloyd visited the show to celebrate Back to the Future Day.

Oct. 21, 2015 was the date that Marty and Doc went to in Back to the Future: Part II, so social media had dubbed yesterday BTTF Day. It seemed only fitting that Fox and Lloyd get to play the characters again, even if just for a few minutes.

At the start of the show, which was taped in Brooklyn, Fox and Lloyd crashed JKL in full BTTF costume. Needless to say, they were a bit disappointed that we still haven’t figured out flying cars. Doc was also sad to know that Johnny Carson has died.

Later during the show, Fox sat with Kimmel to talk about the making of Back to the Future and the sequel. Fox also got to wear Nike’s self-lacing shoes, which was one thing that has actually become a reality from BTTFII.

Fox also had an issue with the Marty action figure that just came out.
