Doc Brown: Marty! You've gotta come back with me!
Marty: Where?
Doc Brown: Back to the future.
Doc opens a trash can.
Marty: Whoa, wait a minute, what are you doing, Doc?
Doc Brown: I need fuel. Quick. Go ahead, quick. Get in the car!
Marty: No, no, no, no, no, no, Doc. I just got here, Jennifer just got here, we're gonna take the new truck for a spin.
Doc Brown: Well, bring her along. This concerns her too.
Marty: Whoa, wait a minute, Doc. What are you talking about? What happens to us in the future? What, do we become assholes or something?
Doc Brown: No, no, no, no, no, Marty. Both you and Jennifer turn out fine. It's your kids, Marty. Something gotta be done about your kids!
Marty: Hey, Doc, you better back up, we don't have enough road to get up to 88.
Doc Brown: Roads? Where we're going, we don't need... roads.
Today is October 21st, 2015 and we're here. We made it to the future.
