Back...to the future!
Every Time Doc And Marty Say “Back To The Future” In The Back To The Future Movies

Because it was only a matter of time, this is a supercut of every time Doc and Marty say “back to the future” in the three Back To The Future movies. Forget about going back to the future, I want to go back to the past and tell younger me to 1) stop being such an idiot and 2) buy as much Bitcoin as possible. I would bring him a sports almanac, but knowing me I’d buy a nudie mag and give him that instead because current me never had future me go back in time and tell past me to stop being such an idiot.

Keep going for the video, as well as a much longer compilation of every reference to time in the movies.
