Continuity mistake: When Mr. Mackey starts to spin Stan around at the end of the "It's Easy, Mmmkay" song, they spin anti-clockwise. Then, from Stan's point of view, they are spinning clockwise, (the background moves to the left). Then, from Mr. Mackey's point of view, they are spinning anti-clockwise again, (the background moves to the right).
Continuity mistake: After Stan joins back up with the rest of the kids, he finds Eric and Kyle on the battlefield as they are climbing out of the trench. In the first shot of Stan before he speaks, Wendy is clearly standing in front of Gregory on his right and Butters is visible in the second row behind Stan. In the next shot from the side, the kids shift so that they are standing further behind Stan than in the previous shot, Gregory is now standing in front of Wendy on her right and Butters has completely disappeared. In the third shot, a girl in a pink shirt, who was not visible before, is now directly behind Stan and Butters has reappeared.
Continuity mistake: When Mole digs out onto the stage, you can see Terrance and Phillip in their chairs, and the helmets they're wearing have a wire which is connected to the chair. Yet in a closeup of Mole talking to Terrance and Phillip, the wire goes straight up, and isn't connected to the chair.
Continuity mistake: When Saddam is packing his suitcase for Earth, you can see a little doll in the case, on the right hand side of it. But in one shot when Saddam gasps because Satan says he's leaving him, the doll is on the left hand side of the case. Straight after that shot though, it's back on the right hand side of the case.
Continuity mistake: When Kenny is brought into the hospital, there is a schedule on the wall next to the door (Dr. No is scheduled to 'Kill Bond'). When Kyle is worried that their Mums will find out that they went to the movie, the Doctor column has vanished from the chart. A little later, the columns are reversed.
Continuity mistake: On the Conan O'Brien show, Terrance and Phillip put on moustaches, then Phillip farts in Terrance's face and Terrance goes flying off the screen with no moustache on. Yet in the next shot of him landing in the drum, he has his moustache back on. (Best viewed in slow-motion)
Continuity mistake: When looking across from Tom's Rhinoplastry you can see the Post Office, and when you look across from the cinema you can see Tom's Rhinoplastry. This would suggest that the Post Office and the cinema are right next to each other, but in any shots showing the front of the cinema, the Post Office is nowhere near it.
Continuity mistake: The first time the South Park boys see the Terrance and Philip movie, their order in their movie theater seats is (from left) Kyle, Stan, Eric, and Kenny. After a couple leave, saying "Well, what do you expect, they're Canadian", a shot from behind shows that Stan and Eric have switched places. In other shots they're in the original positions.
Continuity mistake: In the cinema hall, when we see the South Park kids before the movie starts, you can see what looks like a baby, who we can presume is Kyle's baby brother, sitting next to him to his right. However, at the part in 'Asses Of Fire' where Terrence and Philip are having a farting competition with a traffic police and after a couple left the cinema in disgust, the camera cuts back to the gang but the baby has disappeared. After the gang leaves the cinema 3 hours later, the baby reappears and is seen dangling on Kyle's arm.
Continuity mistake: During the "La Resistance" song, Gregory is singing with the other kids in on group and Cartman, Stan and Kyle are singing in another group. However, as it shows the kids, Satan, the mothers against Canada and the fathers, Cartman, Stan and Kyle and the other kids are all together. They couldn't have been in the group with the other kids the whole time because another kid has appeared next to them.
Continuity mistake: When Saddam says build a statue where Cartman is, Cartman, Stan and Kyle are standing next to each other. Cartman then calls Saddam a butt-f*cker and the V chip makes Cartman electrocute one of Satan's bats. After Cartman realizes he can electrocute Saddam, Kyle says "Yeah, do it Cartman". But Kyle is now a foot away from Cartman.
Continuity mistake: When the boys are in the lunch line and Stan is singing about Wendy, you can see that the "Terrance and Phillip" T-shirts that Stan and Kyle are wearing are mirror images of how they should appear, with the "T&P" written backwards. Also, Kyle's shirt design changes between shots.
