【台词片段】

Joy: Curtis. You and I have a problem. I think we both know how this game works. I complain, and you tell me there's nothing you can do, but we both know that's a big, fat lie, so why don't you just save us both the trouble and type in those special codes that you know you're gonna type in eventually and find me two rooms that are so nice that it turns my night right back around?

Curtis: I'm going to do exactly what you're telling me to do, because I'm a little frightened of you. These are penthouse suites. You can't get any higher than that without going on the roof, and you're not allowed on the roof, because people jump.
