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

Merry Christmas, little fella. We know that you're in there, and that you're all alone.

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

Ma'am, I'm eight years old. You think I would be here alone? I don't think so.

Bless this highly nutritious microwavable macaroni and cheese dinner and the people who sold it on sale. Amen.

- 1.21 gigawatts! 1.21 gigawatts. Great Scott!

- What-what the hell is a gigawatt?

- 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.
