BECAUSE it's rude!

Roman:
[the family are all seated in the cabin's living room and Roman notices Chet at the fireplace]
Now, what are you up to? Chet:
[irritably]
What does it look like I'm up to? Roman:
Well, it looks like you're wanking your crank. Chet:
I'm trying to get a fire going, all right? Roman:
Well, you might as well pour ice cubes in there. You're never gonna get a fire going that way. You don't crumple a newspaper up. [making jerking motions] Roman:
You Twist it! Twist it! Lengthwise to stimulate kindling. That's how you get it going. Chet:
[annoyed]
Maybe, Roman, just maybe, I'm trying to heat the flue. Roman:
[to the others, sarcastically]
Oh, he's heating the flue. Meanwhile, the human beings in the room are freezing to death. Connie Ripley:
[spiteful]
I'm not really cold. Not at all. Kate Craig:
[sarcastic, to Connie]
Oh, thank you for sharing that. Thank you. Chet:
[mockingly]
I'm SO sorry, Roman, forgive me. Why don't you come over here and show me how it's done? You talk a great game. Come on, let's see a little action. After all, you know everything. You know exactly what to do at any given moment. Roman:
[insulted, to Kate]
Katie, you were absolutely right. We should have gone to Europe or maybe even Haiti, or Antartica, or the Dead Sea! Would've had a LOT more fun! [gets up and walks to the other side of the room] Chet:
Is that a fact? Well, nobody forced you to come up HERE, buddy boy. In fact, I don't remember anyone inviting you up here. [to Connie] Chet:
Do you remember inviting him? I sure as hell don't. Roman:
[walking towards Chet]
And what exactly is that statement supposed to mean? Chet:
You figure it out for yourself. Roman:
No, no, you specify, you clarify Just as a common courtesy, if You don't mind. Roman:
[to Roman, without looking up from her sewing]
You know damn well what he means. Connie Ripley:
I think what they're trying to say that we're not welcome! Chet:
[sarcastic]
Oh-ho, what did I hear? We've got a bingo! You DID figure it out, Kate! Roman:
[sneers]
So, it's all starting to finally ooze out. It's very interesting, though, isn't it, Katie? Roman:
Yeah, VERY! Roman:
Especially, since we threw aside OUR plans, and we had a great European vacation planned, threw aside OUR plans to come up here to show these dead-asses how to start learning to have a good time! Thanks a lot for ruining my vacation, Ripley. Chet:
[while trying to light a match, he breaks it in anger]
What WAS that? Ruining your vacation, is that what you said? Oh, come on, I DON'T believe, I don't believe I heard you say THAT. Chet:
[jabs his finger to Chet's chest]
You'd BETTER believe it! Chet:
[jabbing his finger hard into Roman's chest]
DON'T PUSH IT, ROMAN! Chet:
You ain't even seen PUSHING yet! You know what the trouble is with you, Ripley? You wouldn't know a good time if it fell out of the sky, landed on your face, and started to wiggle! Roman:
[seething]
Oh, you got an awful lot of nerve, Roman. A lot of nerve. Roman:
Serves me well. I'M the one with the Mercedes. Roman:
[egging Roman on]
Oh! Ah! Chet:
By the way, is it paid for? Roman:
Are you jealous, CHESTER? Chet:
[jabs his finger into Roman's chest]
DON'T call me Chester! You call me that one more time, you'll be going home with a dent in your forehead! Kate Craig:
[stands up to join Roman]
Oh-ho, yeah, that'll be the day! Kate Craig:
[to Kate]
Would you like one to match his? Roman:
[outraged]
Hey, take your hands off her! [puts up his fists] Roman:
YOU WANT TO GO, RIGHT NOW? Buck Ripley:
[steps in to separate them]
Dad, Dad, it's okay. Nobody's denting anybody. Roman:
Thanks, Bucky. Buck Ripley:
[takes off his scarf and throws into Roman's hands]
Oh, bite the big one, Uncle Roman! Connie Ripley:
[to Buck, scolding]
Hey, don't talk to adults that way! Buck Ripley:
[to Connie]
Why not? Roman:
[to Buck]
BECAUSE it's rude!
