Back to the Future

[Dr. Emmett Brown is doubting Marty McFly's story about that he is from the future]
Dr. Emmett Brown: Then tell me, future boy, who's President of the United States in 1985?
Marty McFly: Ronald Reagan.
Dr. Emmett Brown: Ronald Reagan? The actor?
[chuckles in disbelief]
Dr. Emmett Brown: Then

who's vice president? Jerry Lewis?
[rushing out and down a hill toward his laboratory]
Dr. Emmett Brown: I suppose Jane Wyman is the First Lady!
Marty McFly: [following Doc] Whoa. Wait, Doc!
Dr. Emmett Brown: And Jack Benny is secretary of the treasury.
Marty McFly: [outside the lab door] Doc,

you gotta listen to me.
Dr. Emmett Brown: [opens the door to the lab] I've had enough practical jokes for one evening. Good night, future boy!
[closes the door leaving Marty outside]
Marty McFly: No, wait, Doc. Doc. The-the-the bruise on your head, I know how that happened. You told me the whole story. You were standing on your toilet and you

were hanging a clock, and you fell and you hit your head on the sink. And that's when you came up with the idea for the flux capacitor,
[somberly]
Marty McFly: which is what makes time travel possible.
[Doc opens the door and looks at Marty with a stunned look on his face]
