This is one of my absolute favorite holiday movies! Every December I watch it, probably more than once. My kids have always found it funny, especially since the character Chevy Chase plays reminds them so much of their father! Clark Griswold IS my husband! A few years back, my brother and his family were watching the movie, and actually had to call us on the phone. They were laughing so hard at the part were Clark is trying to string lights on his house and he staples his sleeve to the roof and knocks over the ladder. My brother said it reminded all of them of my husband. Favorite scenes: When the daughter is trying to tell the mom how "sick and twisted" it is to have to sleep with her brother when the grandparents are coming to visit. Clark stringing lights. When they go sledding on the super fast saucer. The scenes with Randy Quaid are hilarious, especially when Clark tells him- "I couldn't have been more surprised if I had woken up with my head sewn to the carpet." Probably not quoted exactly, but close! Chevy Chase is a riot throughout the whole movie, always muttering something funny.
