Factual error: When Mike is meeting with Lydia in her office, you can see an undeveloped hillside from Lydia's office window with sagebrush and other desert shrubs common in New Mexico. However, Lydia's office is in Houston, Texas, where such plants do not grow. Houston also does not sit in the desert, it lies in a coastal plain where it is much greener than Albuquerque.
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.
