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. (00:50:50)Casual Person
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. (01:12:10)Casual Person
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.
