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.
