Back to the Future or The Big Lebowski?

Are you a fan of The Big Lebowski? Of Back to the Future as well? Prove it! Select which quote belongs to which movie and see how good you are:

- We better back up. We don't have enough road to get up to 88.

- Roads? Where we're going, we don't need roads.

If my calculations are correct, when this baby hits 88 miles per hour... you're gonna see some serious shit.

Yeah, well, you know, that's just like, uh, your opinion, man.

That rug really tied the room together.

I love you, but sooner or later, you're going to have to face the fact you're a goddamn moron.

- 1.21 gigawatts! 1.21 gigawatts. Great Scott!

- What-what the hell is a gigawatt?
