Hal: What? Oh, for God's sakes. Can you think of a Christmas reason for stopping somewhere I can sell blood?
Lois: Oh, Hal, don't worry about it. It'll be okay. You just need to find something that's a thousand times better than Disneyland, open on Christmas day and free.
Hal: Just because it's hard, Lois, doesn't mean it's impossible. I am going to make this happen.
Lois: Hal, we don't even have enough gas to get home.
Hal: Yes, we do. I did all the calculations, Lois. We're exactly 40 miles from the point of no return. And I promise you, I will figure out a plan by then. If not, I will turn the van around. Just don't rat me out. Please, honey. It's Christmas.
