Factual error: At the start of the scene where Jimmy films a commercial at the school, kids are shown on the playground. Many of them are wearing leggings or skinny jeans. The episode is set in 2002, when the trend was flare and straight legged jeans. The skinny jeans and leggings trend didn't become widespread until 2009 or 2010.
Character mistake: When Jimmy and the film crew are on the school campus, they are approached by the school administrators. Jimmy mentions an "Annette" who works at the superintendent's office. One of the admin asks the other if they "know an Annette downtown." The superintendent's office is not located in downtown Albuquerque, it is in uptown Albuquerque, several miles east of downtown.
Continuity mistake: When Kim has finished her interview she goes to the roof car park and lights a cigarette whilst the camera shows the street with parked cars. When she reaches into her purse to tear up the WM business card two of the vehicles have disappeared - a white car and a van which had its hazards flashing. All happens in under 8 seconds. In the same scene, when she unlocks her car it is in a bright patch of sunshine, in the close up it's all in shade.
