We know you're probably sick of Back To The Future stories by now but stick with us for this one because it's probably the best of the week.
US talk show host Jimmy Kimmel is doing his show from Brooklyn, New York this week and the 'Back to the Future Day' show was gate-crashed by Marty McFly and Doc Brown.
We've seen plenty of lookalikes in various places this week but the real stars - Michael J. Fox and Christopher Lloyd - showed up to perform a great skit.

The product placement almost ruined it, but Great Scott, it's nice to see those two characters on screen together.
