New this month Continuity mistake: In the very beginning, Butters walks in after Cartman, Kyle and Stan talk about replacing him. Butters and Cartman sit down and talk. Firstly, pay attention to the 'Cow Day' banner behind Cartman. After the camera goes from Cartman talking to Butters then back to Cartman, a letter S is now on the banner. It now reads 'Cow Days.' During the same sequence, look behind Butters. You can see Peter Panda on what looks like a toy box. After a few cuts from Cartman to Butters, now all of a sudden, Clyde Frog is next to Peter Panda on the box.
New this month Character mistake: When the seniors take over the town, they put all the adults into a camp so that they can't stop them, but near the end of the episode, the seniors are surprised that Country Kitchen Buffet is not open. They shouldn't be surprised because if all the adults are in a camp, then there would be no one around to open up the restaurant for the seniors.
Continuity mistake: In the episode "Cat Orgy" when Sheily's boyfriend, Sklar, are playing the song for Sheily while Cartman is hanging on the coat rack you can see of what looks like a picture of Cartman's grandparents hanging on the wall. But when Sheily walks over and flings Cartman up into the ceiling for arguing with her, look at the wall, the picture is completely gone.
Other mistake: When the boys cause a mini tremor by blowing up the girls' base, the time at which it occurs is strange because when they do it, both Stan's parents are at home (even though they both have jobs), Ms. Choksondik and Mr. Mackey are at Choksondik's house getting it on (indicating that school is over) and the other teachers are still at the school.
