Biff Tannen (Thomas F. Wilson): "I can't believe you'd loan me your car without telling me it had a blind spot."
George McFly (Crispin Glover): "Blind Spot?"
Biff: "I could've been killed."
George: "Now... Now, Biff, I never noticed that, uh, the car had any blind spot before when I would drive it. Hi, son."
Biff: "Well, what are you blind, McFly? It's there. How else do you explain that wreck out there?"
George: "Now, Biff, um, can I... can I assume that your, uh, insurance is gonna pay for the damage?"
Biff: "My insurance? It's your car. Your insurance should pay for it. I wanna know who's gonna pay for this. I spilled beer all over when that car smashed into me. Who's gonna pay my cleaning bill?"
