Continuity mistake: In the opening the boys get on the school bus. Stan is on the fifth row, Cartman is on the sixth row, Kyle is on the seventh row and Kenny is on the eighth row and there are another two rows behind them. But in the shot after Cartman says "Ample parking day and night! People shouting howdy neighbor!", Kenny is now on the back row. (00:00:10)
Revealing mistake: When Jimbo asks the children if they want beer, the campfire stays still for two shots.
Continuity mistake: When Ned, Jimbo and Kenny are out on the fishing boat they have a rocket attached to a rack. After firing the rocket the rack still remains, but in the next shot when they head for shore the rack is gone.
Continuity mistake: When Mr. Garrison is carrying around his gun, it is not the wood finished gun with the wood colored hand grip that he bought, it was the other one that had the grey hand grip. (00:14:20)
Suggested correction: He says he will have it (wood finish) then it shows him walking through town. Plenty of time for him to change his mind again.
Perhaps, but later when Stan and Wendy interrupt him, his gun exhibits wood furniture again. Unless he purchased both, some error has been made here.
Continuity mistake: After Mr Garrison announces Kathie-Lee will be presenting an award for Cartman, you see the next scene in the Mayors office. There we can see cleary the curtains are red, then she looks out the window and looking in the office from outside, they are pink, but it goes in the office again and now they are back to red.
Continuity mistake: In one shot, the security guards are on the ground surrounding Kathie Lee, and in the next shot, they are on the truck.
Revealing mistake: Right after Wendy tries to convince the crowd that Cartman's actual paper was 'Walden' with Cartman's name on it, Stan mentions something about Kyle's mom making tuna fish sandwiches. When he does this, you can kind of see him 'lift' off the background.
Continuity mistake: When Mr. Garrison is standing in front of the mirrors with the gun, his hand's position on the gun differs depending on what mirror you're looking at.
Continuity mistake: When Wendy asks the crowd where they all are going, the wide shot shows that Kyle is nowhere near the stage. When it cuts Kyle is standing right next to Wendy.
Continuity mistake: When Mr. Garrison asks Officer Barbrady where he can get the best shot or view of Kathy Lee. Barbrady's pants are black. In the next scene when Barbrady takes the next guy's camera his pants are blue.
Continuity mistake: During the rehearsal of the play, Kenny's Indian feather is blue. When the tepee crushes him, his feather is now yellow.
Continuity mistake: When Wendy finds her report paper, it has "good effort" and her grade written in red marker pen on it, with a short note underneath it also written in red pen. In the next shot the "good effort" and grade number are still on the paper but the note underneath has vanished.
Continuity mistake: When Cartman throws a tantrum and makes his Mum go to the store to get him Weight Gain 4000, he throws his Cheesy Poof's bag to the floor. In the next shot it's in his hand again.
Continuity mistake: When Mr. Garrison is having the kids rehearse the play, Bebe is standing in front of Kenny. When they cut to a closer view she is no longer there but should still be visible. She returns in the next wide view.
Big Gay Al's Big Gay Boat Ride - S1-E5
Other mistake: You can see Token in the episode as white, not black.
