Back to the Future (1985) runs on lines built like clockwork setups: 'Roads? Where we're going, we don't need roads' closes the film as a promise of sequels, and 'Great Scott!' made Christopher Lloyd's Doc Brown a one-man exclamation. '1.21 gigawatts' is mispronounced 'jigowatts' throughout -- an accepted physics-community pronunciation of the era that the script fixed in amber.
Roads? Where we're going we don't need...roads.

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
Wait a minute, Doc, are you trying to tell me that my mother has got the hots for me?
Marty McFly
Wait, hold on Doc, are you telling me that you built a time machine...out of a Delorian?
Marty McFly
