Dr. Emmett Brown: [Deleted Scene, Doc Brown uses a sound fork and hits the time machine with the sound fork and frantically steps back] I knew, I knew it, I knew it. Marty McFly: Doc, do you have a 75-ohm matching transformer? Dr. Emmett Brown: What? Marty McFly: [Realizing where in time he is] Not invented yet. That's right. Dr. Emmett Brown: [Walks over to his future self's suit case] So, these are my personal belongings, huh? Marty McFly: Yeah. Dr. Emmett Brown: [Opens up the suit case and picks up a hair dryer] What's this thing? Marty McFly: It's a hair dryer. Dr. Emmett Brown: A hair dryer? Don't they have towels in the future? Dr. Emmett Brown: [Picks up a pair of underwear] Oh, look at these underpants. They're all made of cotton. I though for sure we'd all be wearing disposable paper garments by 1985. Dr. Emmett Brown: [Picks up a Playboy Magazine] What's... this? [Looks at the magazine] Dr. Emmett Brown: [exclaims] Suddenly, the future's looking a *whole* lot better.
