1. Aunt Bethany
   Cousin Eddie
2. Clark Sr.
   Margo Chester

Aunt Bethany brought her cat to Christmas, and, unfortunately, it didn't have the best time over the holiday season. Bethany was played by actress Mae Questrel, who provided the voice for Betty Boop back in the 1930s.

   Rusty
2. Ellen
   Clark

The scene in which the grandparents arrive is a hectic montage of everyone talking. Audrey, played by Juliette Lewis, tells her mom she doesn' want them sleeping in her room. Lewis and her movie brother Johnny Galecki reunited, this time as a couple, on the show "The Conners."

1. Rusty
   Clark
2. Eddie
   Snot

In the entire "Vacation" film series, Clark's nickname is "Sparky." Generally, his wife is the only one who uses it. There's never been a particular reason given for why she calls him that, though.

1. Rocky Johnson
   Clark Griswald Sr.
2. Clark Griswald
   Uncle Lewis

Uncle Lewis's terrible toupee is one of the best sight gags in the movie. Lewis was played by veteran actor William Hickey, who many people know more for his voice than his face. Hickey was Dr. Finklestein in "The Nightmare Before Christmas."

1. Cousin Eddie
   Rocky Johnson
2. Todd Chester
   Uncle Lewis

Clark's neighbor Todd has to endure living next to Clark, and he definitely suffers for it. When Clark falls off the roof, he hits the eaves and breaks them, which shoots a massive icicle through Todd's window into the stereo. Played by Nicholas Guest, he's well-known for his voice acting roles in video games and anime like "Cowboy Bebop."

1. Snot
   Eddie
2. Rusty
   Ruby Sue

Cousin Eddie is kind enough to bring a massive rottweiler named Snot to the Christmas party. The dog does its fair share of destruction in the house tarting by drinking the water from under the tree and later by chasing a squirrel around.

1. Rusty
   Eddie
2. Catherine
   Ruby Sue

Grandma Frances is surprised to see Ruby See doesn't have crossed eyes anymore. Eddie goes on to explain that the girl fell down a well, which crossed her eyes in the first place, then got kicked by a mule, which uncrossed them.

1. Margo Chester
   Frank Shirley
2. Cousin Eddie
   Grandpa Art

The first character who says anything in the movie is the Griswold's neighbor Margo Chester, played by "Seinfeld" and "Veep" star Julia Louis-Dreyfus. She insults the Griswold's Christmas tree when she comes home with her husband.

1. Cousin Eddie
   Grandpa Art
2. Cousin Catherine
   Ruby Sue

Grandpa Art, ever the positive influence, points out that while the lights are on, they're not twinkling. Art was played by E.G. Marshall, who had dozens of huge roles over the years, including as the President in "Superman II."

1. Grandpa Art
   Clark Sr.
2. Cousin Eddie
   Mr. Shirley

Cousin Eddie is afraid to use Clark's lubricant on his sled because he has a plastic plate in his head and doesn't want to risk a head injury. Randy Quaid played the character of Cousin Eddie in four different movies.

1. Uncle Lewis
   Cousin Eddie
2. Rusty
   Clark

Clark wakes up early to try to hide some gifts in the attic and pulls the ladder down only to have it hit him square in the face. He ends up being stuck up there when Grandma Frances puts the ladder back up.

1. Grandpa Clark
   Uncle Lewis
2. Aunt Bethany
   Grandma Nora

Aunt Bethany is celebrating her 80th Christmas, so Clark asks that she give the blessing before the big dinner. She offers up the Pledge of Allegiance instead, but it still gets everyone involved.

1. Todd Chester
   Frank Shirley
2. Ruby Sue
   Art Smith

In an effort to be helpful, Cousin Eddie kidnaps Clark's boss Frank Shirley and brings him to the house. Shirley was played by Brian Doyle-Murray, who's the real-life brother of actor Bill Murray.

1. Rocky Johnson
   Cousin Eddie
2. Uncle Lewis
   Snot

When Uncle Lewis lights up a cigar, the entire tree poofs out of existence when the flame from the match hits it, no doubt thanks in some small part to Snot drinking the water to dry the tree out. Lewis ends up lit on fire as well, but he doesn't notice.

1. Clark
   Cousin Eddie
2. Uncle Lewis
   Rusty

When the lights go out on the tree, Clark is the one who plugs them back in, unaware that Bethany's cat unplugged them by chewing on the cord. The scene was going to be cut out of fear people would complain, but test audiences said it was the funniest scene in the movie.

1. Ruby See
   Cousin Catherine
2. Clark
   Aunt Bethany

Aunt Bethany may not be super on the ball, but she does hear the squirrel before anyone else does. The production team had hired a trained squirrel for the scene, and it actually died the day before it was needed, so they just used a random, untrained squirrel instead. He did a convincing job.

1. Ruby Sue
   Rocky Johnson
2. Uncle Lewis
   Aunt Bethany

Clark is at the window fantasizing about Mary again when Ruby Sue catches him and thinks he's Santa for a moment. Ruby Sue was played by actor Ellen Latzen, who got her start in the massively popular "Fatal Attraction."

1. Ellen
   Eddie
2. Clark
   Audrey

After Clark gets stranded in the attic, it's his wife Ellen who sets him free later on. Beverly D'Angelo played Ellen in every one of the Griswold "Vacation" movies, including the reboot.

1. Ellen
   Catherine
2. Audrey
   Frances

Clark thanks Catherine for making a great-looking turkey before he carves into it, and it sort of crumbles like a mummified monster. Miriam Flynn played the role of Catherine and, like many members of the movie's cast, is probably better known for her voice acting in movies like "The Land Before Time."

1. Bill
   Mr. Shirley
2. The delivery guy
   Todd

There's a very brief moment when a character comes to the door to deliver Clark's long-awaited Christmas bonus. The delivery guy tries to read Clark's name and comes out with "Grisman" instead of "Griswold."

1. Cousin Catherine
   Helen Shirley
2. Aunt Bethany
   Bill

Helen Shirley, the wife of Clark's boss, calls the police after Eddie kidnaps her husband. Natalia Nogulich plays the part, and she's likely best known for her numerous appearances on "Star Trek: The Next Generation" and "Deep Space Nine" as Admiral Alynna Nechayev.

1. Rocky
   Ruby Sue
2. Catherine
   Clark

Eddie and Catherine's son Rocky Johnson isn't much of a talker, and, as Eddie points out, you may want to avoid hs mouth anyway thanks to some lip fungus. Rocky was played by Cody Burger, who only appeared in four films as a child actor before going to school and leaving it all behind.

1. Clark Sr.
   Audrey
2. Rusty
   Eddie

After Clark finds out he's not getting a bonus, he very much loses his cool. He grabs a chainsaw to cut down a tree from the yard, and Rusty takes a moment to try to talk his dad out of it. It doesn't last very long.

1. Grandma Nora
   Cousin Catherine
2. Ellen
   Audrey

Clark's mother Nora faints when the squirrel leaps out of the tree. Later, when Clark says he plans to trap it in a coat and crush it with a hammer, Grandma Frances also faints. It's quite a traumatic event.

1. Lisa
   Mary
2. Joan
   Sharon

It wouldn't be a "Vacation" movie if Clark wasn't acting lecherous, apparently. In this one, Clark gets flustered talking to a woman named Mary at a department store and claims he's divorced. Mary is played by actress Nicolette Scorsese, who hasn't had a role since the year 2000.

1. Margo
   Clark
2. Eddie
   Uncle Lewis

Julia Louis-Dreyfus' Margo comes over to the Griswold house to give Clark a piece of her mind. Unfortunately, the squirrel, pursued by the dog, is right at the door, and both of them jump her at the very same time.

1. Cousin Eddie
   Aunt Bethany
2. Rocky Johnson
   Ruby Sue

There are some lights in the sky after the SWAT raid that Ruby Sue thinks is Santa Claus. Clark corrects her and says it's the Christmas Star. Uncle Lewis corrects Clark and says it's gas from the sewage treatment plant.

1. Cousin Eddie
   Aunt Bethany
2. Rocky Johnson
   Ellen

After the lawn Santa explodes, Aunt Bethany leads everyone in "The Star-Spangled Banner." Everyone except Eddie's son Rocky Johnson. The character never opens his mouth to speak once in the entire film.

1. Clark
   Rusty
2. Cousin Eddie
   Frank Shirley

Russ "Rusty" Griswold is the son of Clark and Ellen, and he was played by Johnny Galecki. This was before Galecki got his big role on "Roseanne" and then his much bigger role on "The Big Bang Theory."

1. Eddie
   Art
2. Bill
   Frank

Clark's coworker Bill is played by character actor Sam McMurray. In the first scene that takes place at Clark's office, they talk about Christmas bonuses. McMurray was actually the first-ever guest star to appear on "The Simpsons."

1. A cop
   Cousin Eddie
2. His wife
   Clark

After the police arrive, Clark's boss, Mr. Shirley, explains he suspended the Christmas bonuses, and the police officer on scene tells him it's pretty low and then begins a threat (that he never really finishes) about what he'd do with a rubber hose. The character was played by Alexander Folk, who's been cast as a cop in dozens of movies and TV shows.

1. Clark
   Rusty
2. Audrey
   Ellen

At the beginning of the movie, Clark is driving and singing Christmas carols with Ellen while the kids remain silent. Ellen pauses a moment to refer to the song as beautiful, making her the first character actually to have a speaking line in the film.

1. Grandpa Art
   Cousin Eddie
2. Grandpa Clark Sr.
   Rusty

Clark asks his dad Clark Sr. if he plans on reading the Christmas poem, but his dad declines, telling him that he should do it. He almost gets through the poem, too, until Eddie shows up with Clark's kidnapped boss.

1. Audrey
   Nora
2. Ellen
   Frances

Grandma Nora is played by Diane Ladd, who has been a massive presence in Hollywood with well over 100 credits to her name. She's had several Academy Award nominations in her career and is also the mother of Laura Dern.

1. Grandma Frances
   Grandma Nora
2. Grandpa Clark

Grandma Frances Smith, Ellen's mom, is played by Doris Roberts, who is most well-known as Ray's mother on "Everyone Loves Raymond." As the family piles into the house, she forces a kiss on each of Rusty's cheeks.
