NATIONAL LAMPOON'S CHRISTMAS VACATION (1989)

PREMISE This time, Clark Griswold (Chevy Chase) and his family are spending their vacation at home, at a house overstuffed with wacky relatives.

BAH, HUMBUG! MOMENT So many to choose from: the deflating turkey; the electrocuted cat; the septic explosion...

MEMORABLE QUOTE ''We're gonna press on, and we're gonna have the hap, hap, happiest Christmas since Bing Crosby tap-danced with Danny f---ing Kaye,'' Clark tells his miserable relatives. ''And when Santa squeezes his fat white a-- down that chimney tonight, he's gonna find the jolliest bunch of a--holes this side of the nuthouse.''
