Continuity: In the cemetery scene where Kyle calls the emergency hotline and Stan and Cartman hold off the zombies, in the shot where Kyle's hand holding the Worcestershire Sauce is shown in close-up, his gloves are shown as green instead of white, which they are while Kyle is in his vampire costume.

Continuity: In the opening scene, the trees in the background keep moving between shots.

Continuity: When Kyle cuts Kenny in half, we see a skull behind him, but in the other scenes, the skull is to his right.

Continuity: During the scene where Chef goes to see the Mayor and Officer Barbrady, there is a shot from outside, where a pumpkin is visible in the window. But when Chef goes inside, there is no pumpkin.

Continuity: At the end when the airplane hits Kenny, there is a gravestone with a cross on it behind him, but all the time when the other three boys were talking, none of the gravestones behind them had crosses.

Continuity: Tom's Rhynoplasty appears between two different sets of buildings in the street shots.

Revealing: When Cartman walks in on Sally Struthers eating the cake, the cake has holes in it, and part of her hair goes in front, and part of it is visible through the cake. All of the other slices have holes in the same place as well.

Other: I think it's this episode i can't remember off hand but you can see Token in the episode. White, not black.

Continuity: When the town are protesting outside the Mayor's office, the woman at the front of the Nativity protesting group is wearing a purple shirt. A few seconds later, she is with the group against the cutting-down of Christmas trees wearing a completely different shirt (white with a Christmas tree in a red circle with a line through it).

Continuity: When Mr. Hankey is dancing around Kyle's bathroom there are some poo marks where Mr. Hankey never even touched.

Continuity: In the scene where Mr. Garrison is telling the students to to get in place for the play, Kenny is seen in the group. Despite the fact that he is supposed to be taking the star or the ceiling at that point. He is then seen seconds later climbing down the ladder with the star.

Continuity: Halfway through the episode, Blue Mega-Man turns into Green Mega-Man

Continuity: When Mr. Garrison returns to the classroom with his new face and does the posing to "Shadow Dancing," it flashes back to the students and Wendy is dressed in her normal clothes instead of the black leather she wore to impress Stan. Next time it shows her, she's back to normal.

Continuity: When Stan pukes on to the desk when Miss Ellen says his name at first, it is pink. Then when the camera cuts back to him, it is brown. Then when he pukes the second time and Kyle says "You had waffles for breakfast huh?" it is pink again.

Continuity: At first the football team is mentioned as "The 1988 Denver Broncos" but throughout this episode and its sequel, they are "The 1992 Denver Broncos."

Continuity: The video sent in by Stans granddad of Kenny getting hit by the train doesn't match what actually happened.

Plot hole: Stan's grandad submits the video of Kenny being hit by the train. This gets through into the final, which shocks Stan and Kyle. But shortly the clip would have had to get through to the final by another episode, so shortly Stan and Kyle wouldn't have been so surprised. The video couldn't have been submitted before, as Stans video was submitted first.

Continuity: Chef's car outside Hells Pass Hospital is almost covered in snow the first time it is seen. However a car seen sitting outside the America's Most Wanted studio in South Park a few minutes later has no snow on it whatsoever.

Other: When Mackey's eyes are pink, so are his glasses.

Factual error: When Mr. Mackey, Principal Victoria, and Nurse Gollum are eating dinner with the Broslofskis, notice pork on the table. Since the Broslofskis are practicing Jews, they would have not allowed unclean food (such as pork) in their home.
