Back to the Future

Marty McFly's having the time of his life. The only question is -- what time is it?

"Wait a minute, Doc. Ah... Are you telling me you built a time machine... out of a DeLorean?"
"The way I see it, if you're gonna build a time machine into a car, why not do it with some style?"

    --  Marty and Doc
 

"If my calculations are correct, when this baby hits eighty-eight miles per hour... you're gonna see some serious shit."

    --  Doc
 

"He's a very strange young man."
"He's an idiot. Comes from upbringing. His parents are probably idiots too. Lorraine, if you ever have a kid that acts that way I'll disown you."

    --  Stella and Sam Baines, Marty's grandparents
 

"Then tell me, 'future boy,' who is president in the United States in 1985?"
"Ronald Reagan."
"Ronald Reagan? The actor?  Who's Vice President? Jerry Lewis?"
"What?"
"I suppose Jane Wyman is the first lady. And Jack Benny is secretary of the treasury. I've had enough practical jokes for one evening. Good night, future boy."

    --  Doc and Marty
 

"So why don't you make like a tree and get outta here."

    --  Biff Tannen
 

"I'm sure in 1985, plutonium is available at every corner drugstore, but in 1955 it's a little hard to come by."

    --  Doc
 

"Great Scott!"

    --  Doc
 

"Calvin? Wh... Why do you keep calling me Calvin?"
"Well, that is your name, isn't it? Calvin Klein? It's written all over your underwear."

    --  Marty and Lorraine
 

"If you ever have kids and one of them when he's eight years old accidentally sets fire to the living room rug, go easy on him."

    --  Marty
