Revealing mistake: When Sheila asks if Terrance and Phillip have any last words, Phillip says, "Last words, how's about get me the f**k out of this chair!" When he does, his arm leaves the arm of the chair and goes through the restraint, which reappears instantly after. (01:03:00)
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. (00:04:30)
Continuity mistake: In the long shot Stan is at the top of the steps singing 'there's a bunch' and you see him wobble down the steps, it then cuts to a close up and Stan is back at the top of the steps singing 'of birds in the sky' as he wobbles down the steps again. (00:00:30)
Continuity mistake: When Stan knocks at Kenny's, Kenny goes to put his orange hooded coat on, and as he pulls it on his orange shorts appear on him, although he never put them on. (00:01:50)
Continuity mistake: When Gregory is explaining their attack at the USO show, he has toy soliders and cans on a table. Between a wide shot and a closeup, the 'Peas' can on the table moves. (00:47:05)
Continuity mistake: When Gregory and Wendy enters Carl's Warehouse, the banner with the words "Viva la resistance" painted on it has disappeared. (00:45:50)
Continuity mistake: In the scene in Hell when Kenny opens the door to Satan's bedroom he pulls the door outward, but when it goes to a frontal view of Kenny the door is open inwards. (00:38:05)
Continuity mistake: The little sun awning over the roof of Tom's Rhinoplasty is grey in some scenes, and brown in others. The actual colour of the building itself changes slightly during the course of the film.
Audio problem: When Satan and Saddam leave the room, after the 'I can change' song, Saddam says "I love you" yet his mouth never moves. (00:54:00)
Continuity mistake: During the briefing of the American soldiers before the war with the Canadians, watch the background whenever we cut back to the big-general. The soldiers change positions on a fairly regular basis.
Continuity mistake: Sheila Broflovski shoots Philip in the middle of the "P", but when the blood starts flowing on the ground, the bullet hole is on the letter itself. (01:11:10)
Continuity mistake: In the scene where Mr Mackey is conducting the class on not swearing, we never see Kenny in the scene. Then all of the sudden we see him in the musical number. Where was he before? (00:14:50 - 00:16:10)
Continuity mistake: The whole time we see The Mole, he has nothing on his arms. His watch only appears when he wants to synchronise watches with the boys. (00:53:25 - 00:59:00)
Continuity mistake: In the scene where Mr Mackey is teaching the kids not to swear, as he starts his song "It's Easy Mmm-kay", the rose on the piano is on the left hand side. By the end of the song it's on the right. (00:14:48)
Continuity mistake: When Cartman is in his bedroom, there's something besides his backpack that looks like books but when his mother is gone, it's now a mirror and a rope. (00:41:20)
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. (00:05:00 - 00:06:55)
Continuity mistake: Stan asks his mum for some money to see a movie and his mum puts a pencil down on the table. Yet when she gives Stan the money, the pencil is much shorter. (00:01:20)
Continuity mistake: When Kenny and Stan pass in front of the church, the doors are closed but they're opened the shot later, when Kenny sings. They're closed again after that. (00:02:25)
Factual error: In the film we see Bill Clinton sign a document with his right hand. Bill Clinton is actually left handed. (00:34:10)
Chosen answer: They don't believe him, so they're making a sappy joke about him "still being here all around us."
