the scene in question happens before they fix anything. it's when the dolorean was "stolen" by Biff which at this point Marty and Doc were oblivious to.
Actually all the confusion came back when that scene came on. And yes how times have changed, the scene were the brothers wanted proof that the geek was making out with Samantha and they ask for video and he says no way cuz it would end up getting copied and end up on cable. They bet 12 floppy disks for christs sake! FLOPPY DISKS!!
Sorry to bump this thread up but has anybody seen the movie "Fresh?" If so, I have some questions about some scenes in that movie.
