Back to the Future or Dumbo?

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

- Is that a monkey in your desk?

- Just for emergencies.

- 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.

Never do anything I tell you, without checking with me first.

- 1.21 gigawatts! 1.21 gigawatts. Great Scott!

- What-what the hell is a gigawatt?

Last time I checked, they invented the stairs!

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