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.
