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.
Revealing mistake: Mr. Mackey's glasses do not have the part that goes over his nose unless he is looking sideways, then it suddenly appears. (00:17:40)
Continuity mistake: When Miss Chokesondik first lectures the girls on STD's the words "Sexually Transmitted Diseases" appear on the blackboard although partially obscured as it is a narrow shot of the teacher. The view then changes to a wide shot of the blackboard and nothing is written on it. Miss Chokesondik then proceeds to write "Sexually Transmitted Diseases" on the board. (00:05:35)
Continuity mistake: In the background we see an ambulance with "South Park Hospital" written on it. It is supposed to be called "Hells Pass Hospital." (00:19:55)
Continuity mistake: During the first classroom scene, Token is in the back with Kenny partially in front of him, but when we see the closeup of the projector with Token in front of it, we don't see Kenny anywhere. (00:04:45)
Answer: Essentially Stan was trying to return the blender that his dad, Randy, had bought because he knew his parents couldn't afford the extra debt. The blender, which represented mortgage-backed securities, had been bought on payment plan, meaning Randy had to make monthly payments, with interest, on something that wasn't essential. The episode represented the recession that was occurring at the time, including the housing bubble and mortgage crisis going on, so there's a lot going on. However, the payment plan (which is to say the debt) had been sold to another company by the store that sold Randy the blender. (To explain why, because of the recession, the store needed cash on hand, and they would only be getting a little money each month, if Randy paid his bill. So the store sells the debt to a company who gives the store the money upfront. Think of the J.G. Wentworth commercials, "I have a structured settlement, but I need cash now".) Because the store sold the debt, in ridiculous fashion, Stan had to return the blender to the company that bought the debt, although they too sold the debt to another company. Finally he gets to the U.S. treasury who tells him his blender is worth $90 trillion (again a ridiculous exaggeration) meaning that the debt owed is greater than the product is worth and to deride the way government agencies set up their budgets (which requires much more complex economic lessons). Kyle's whole point was people shouldn't fear the economy or see it as a vengeful being, but continue to spend and live as they normally do. Economically speaking, not spending money during a recession creates a longer lasting recession, and to solve a recession, people should spend money, although people and businesses shouldn't acquire debt during a recession because interest rates are higher. But on a personal level, individuals are fearful of losing their jobs during a recession, so they save money in case that should happen. But again, this is complex economics lesson.
