[Todd and Margo Chester, the Griswold’s yuppie neighbors, appear]
Todd: Hey Griswold. Where do you think you’re gonna put a tree that big?
Clark: Bend over and I’ll show you.
Todd: You’ve got a lot of nerve talking to me like that Griswold.
Clark: I wasn’t talking to you.
Ellen: What are you looking at?
Clark: Oh, the silent majesty of a winter’s morn… the clean, cool chill of the holiday air… an asshole in his bathrobe, emptying a chemical toilet into my sewer…
[Eddie, in the driveway, is draining the RV’s toilet]
Eddie: Shitter was full.
Clark: Ah, yeah. You checked our shitters, honey?
Ellen: Clark, please. He doesn’t know any better.
Clark: He oughta know it’s illegal. That’s a storm sewer. If it fills with gas, I pity the person who lights a match within ten yards of it.
Clark: The most enjoying traditions of the season are best enjoyed in the warm embrace of kith and kin. Thith tree is a thymbol of the thpirit of the Griswold family Chrithmath.
Clark: Whew, it’s warm in here.
Mary: Well you have your coat on.
Clark: Ah yes I do, why is that?
Mary: Because it’s cold out.
Clark: Yes it is, it’s a bit nipply out. I mean nippy out, what did I say, nipple? Huh, there is a nip in the air.
I could go on…
