National Lampoon's Christmas Vacation

Factual error: Prior to the cat being electrocuted, Clark is seen plugging the lights into a 110 volt outlet. However, when Rusty resets the breaker, it is a double pull breaker that is reset, which typically provides 220 volts, and the breaker is off instead of tripped. (01:09:00)

Factual error: In the scene where Clark is working on the lights the full moon is shown. This is December 14th according to the advent calendar. On December 24th when Santa's sleigh goes sailing over the moon, it is still full.

Factual error: Even though this movie takes place at Christmas and there is lots of snow around the outside of the house, you can tell this was filmed during the summertime due to the short shadows in some outside scenes. At Christmas time, shadows are longer all day long.

Factual error: The family is reacting to where Clark went flying down on his saucer, ending up in a Wal-Mart. With the speed and length of the trip, he would've been out of sight in seconds. There was no way that they could see him from where they were.

Factual error: When Clark is sliding on the saucer, he shoots out a shower of sparks when he crosses the street. Those old saucers were made of aluminum, and aluminum can't create sparks like other metal does.

Continuity mistake: When Uncle Lewis and Aunt Bethany have just arrived and Aunt Bethany says, "Oh dear, did I break wind?" Ellen helps Aunt Bethany fully remove her coat. Seconds later, within the same scene, Ellen is still helping Bethany off with her coat. (01:02:45)

Clark: Worse? How could things get any worse? Take a look around you, Ellen. We're at the threshold of Hell.

Trivia: Clark Griswold in the attic watching old movies dressed in a woman's turban and gloves to keep warm is not only funny but a reference to the Norma Desmond character from "Sunset Boulevard", who watches her old films to remember her Hollywood glory days.

Question: When Clark gives his boss a Christmas present, he is told to put it with all of the others. There are plenty of presents there, but they are all the same, as they have the exact same shape. What are these presents?

Answer: They are desk organizers.

I'm wondering maybe it was one of the gags in the movie where the boss got the same gift from all the employees. I know there's a lot of gags in the vacation movies.

Answer: I've seen them in stores, it's a desk pen set with a matching business card holder.

Chosen answer: We don't know what is in the packages, but we can assume they are all the same, small, generic gift.
