6.  During a scene early in the movie Clark never rinses or puts the dishes in the dishwasher.

7.  Beverly  D'Angelo is actually a very good singer, despite what appears in the family sing-a-long scenes.

8.  During the scene where Clark is trying to find the gas cap for the Family Truckster he didn't intend to throw it.  The plate nearly hit the actress behind him who was filling her tank.   The look of concern on his face is genuine.

9.  Christie Brinkley was just becoming a superstar in the modeling industry.  She only appeared in a few scenes, but traveled with the cast and crew for much of the shoot.  It was her first movie credit.  She was also in the sequel "Vegas Vacation."

10.  Cousin Eddie (Randy Quaid) based his trademark tongue clique on a guy he knew in school and marked every spot on the script where he used it.
