Biff: You’re so gullible, McFly!
George: Last night, Darth Vader came down from the planet Vulcan and said that if I didn’t take Lorraine to the dance, that he’d melt my brain.
Marty McFly: Wait, hold on Doc, are you telling me that you built a time machine…out of a Delorian?
Marty: Let’s see if you bastards can do 90.
Marty McFly: Wait a minute, Doc, are you trying to tell me that my mother has got the hots for me?
Dr. Emmet Brown: Precisely.
Marty McFly: Wow, this is heavy.
Dr. Emmet Brown: There’s that word again, “heavy.” Why are things so heavy in the future? Is there a problem with the earth’s gravitational pull?
Dr. Emmet Brown: Roads? Where we’re going we don’t need…roads.
Marty: What the hell is a jigawatt!?
Nobody calls me chicken.
