Back to the Future Part III

Doc: "Marty, you're going to have to do something about those clothes. You walk around town dressed like that, you're liable to get shot."
Marty "Or hanged."
Doc:" What idiot dressed you in that outfit?"
Marty: "You did."

Marty McFly: "Hey, Doc! Where you goin' now? Back to the future?"
Doc: "Nope. Already been there."

Jennifer: "Dr. Brown, I brought this note back from the future and... now it's erased."
Doc: "Of course it's erased!"
Jennifer: "But what does that mean?"
Doc: "It means your future hasn't been written yet. No one's has. Your future is whatever you make it. So make it a good one, both of you."
Marty: "We will, Doc."
