“What’s wrong, McFly? Chicken?” No, He’s a Dog
What if Back to the Future director Robert Zemeckis changed the casting of Marty McFly for the third time and replaced Michael J. Fox with a dog? That’d be one cute movie, as evidenced by this cosplaying dog (via Reddit). It’d also be insanely silly. How silly? About as silly traveling to the future to fix an easily preventable event that won’t happen for 30 years — lookin' at you Part 2. So it’d be fun, but kinda pointless when you actually think about it.
I've got two words for people in the comments section: Barky McFly. There, I beat you to it.
