Zork: Well, look at it this way, honey, this is a part of the universe we never get to see.

Zork: No, that's bad. I mean, we can't close our eyes to the plight of the Earth. Kids, are you noticing all this plight? This'll just make us appreciate what we have. (There's a gunshot somewhere near the space ship, followed by a scream) Roll 'em up!
