Miss Teacher Bangs a Boy - S10-E10
Continuity mistake: Season 10, Episode 10: "Miss Teacher Bangs a Boy". When Miss Stephenson is drawing shapes on the blackboard, she draws a circle and a square only, and then is disrupted by Cartman. At the end of the scene where she is erasing the board, a triangle is now on the board with no time to draw it.
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.
