Scott Tenorman Must Die - S5-E4
Continuity mistake: When Kyle and Stan show up to the Chili Con Carnival, we see in the background a woman with a little girl walking towards the right and Kyle and Stan at the left walking towards Eric's booth. When Kyle and Stan get there in the next shot, the woman and the girl are still walking, but they are in the same place as they were when the shot cut. This makes Kyle and Stan able to walk very fast apparently.
Miss Teacher Bangs a Boy - S10-E10
Continuity mistake: Season 10, Episode 10 "Miss Teacher Bangs a Boy". In the scene where Cartman and his crew park the SUV outside the Hilton behind an orange car. In the next shot when Cartman and his crew are running in, the SUV is gone, only to return in the next scene. (00:18:25)
Continuity mistake: When Cartman is planning, in the shot from behind him when he's on the computer there is a cup with a red and yellow pencil in it, the red is on the right and the yellow is on the left. Yet when it goes to looking at Cartman from the other way the crayons must've swapped positions because now they are the other way around.
Continuity mistake: When Jimmy is about to use the steroids, there is a shot of the pills. Then when he uses the steroids we can see the order of them the way they were layed out on the original shot has changed. (00:05:35)
Continuity mistake: When Cartman finds the cotton bud, whilst he's examining it, the controller changes positions in between shots.
Butters' Very Own Episode - S5-E14
Continuity mistake: Butters' mom is holding a knife, pointed at her shoulder, but in the very next shot it is down near the cucumber, and then goes back.
Continuity mistake: In many episodes, the word "chef" on Chef's apron goes from lower case to upper case, within the same episode and usually happens instantly between shots with no time for him to change the apron. (00:11:10)
Continuity mistake: When Miss Chokesondik first lectures the girls on STD's the words "Sexually Transmitted Diseases" appear on the blackboard although partially obscured as it is a narrow shot of the teacher. The view then changes to a wide shot of the blackboard and nothing is written on it. Miss Chokesondik then proceeds to write "Sexually Transmitted Diseases" on the board. (00:05:35)
Scott Tenorman Must Die - S5-E4
Plot hole: When Scott Tenorman shows the other kids a video of Cartman doing his "piggy" act, the angle of the video shot shows that it could only have been taken from the place where Scott was standing when Cartman originally did it - but Scott is seen at that time to have no video camera or any way to have recorded this.
Mr. Garrison's Fancy New Vagina - S9-E1
Continuity mistake: Kyle and the rest enter the basketball centre. Three people are behind them, then when the shot changes they're gone. (00:02:00)
Audio problem: Just before Kenny explodes from eating all of Mr. Broflovski's antacid tablets, we hear Kyle, Stan and Cartman shout out Kenny's name. One problem - Cartman isn't in the room with them. He isn't even on their debate team. (00:10:35)
Continuity mistake: 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.
Revealing mistake: 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.
Continuity mistake: When Mr. Garrison is standing in front of the mirrors with the gun, his hand's position on the gun differs depending on what mirror you're looking at.
Mr. Hankey, the Christmas Poo - S1-E10
Continuity mistake: 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.
Cat Orgy (1) - S3-E7
Continuity mistake: When Cartman gets his kitty the catnip from under the kitchen sink, a yellow plate rack full of plates appears on the worktop next to the sink that wasn't there in previous shots.
Miss Teacher Bangs a Boy - S10-E10
Continuity mistake: Season 10, Episode 10: "Miss Teacher Bangs a Boy". When Miss Stephenson is drawing shapes on the blackboard, she draws a circle and a square only, and then is disrupted by Cartman. At the end of the scene where she is erasing the board, a triangle is now on the board with no time to draw it.
Continuity mistake: When Mr. Garrison is carrying around his gun, it is not the wood finished gun with the wood colored hand grip that he bought, it was the other one that had the grey hand grip. (00:14:20)
Suggested correction: He says he will have it (wood finish) then it shows him walking through town. Plenty of time for him to change his mind again.
Perhaps, but later when Stan and Wendy interrupt him, his gun exhibits wood furniture again. Unless he purchased both, some error has been made here.
Coon vs. Coon and Friends - S14-E13
Deliberate mistake: S14 Ep13 Coon vs. Coon & Friends: in the South Park universe, Canadians are depicted as looking the same (beady eyes, stick legs, heads sliced in half). Since Justin Bieber is Canadian, he should look similar to Terrance and Philip instead of having a normal face and body.
Suggested correction: I don't see how this is a mistake, deliberate or otherwise. While the creators of the show have established that to be the appearance for Canadian characters, they are well within their rights to invoke artistic license whenever they see fit. Is it also a mistake that Mel Gibson and Saddam Hussein have photorealistic faces when the majority of other characters have been established as having cartoon faces?
Cat Orgy (1) - S3-E7
Continuity mistake: When Shelley and Skyler are in the kitchen, there's a plate on the table with pizza crusts on it. Between closeups and wide shots the crusts continually switch from the left to the right side.
