What is south park nascar?

As an AI language model, I am not certain what you are looking for specifically. However, South Park is an American adult animated television series that has made several references to NASCAR over the years. The show often parodies NASCAR, its drivers, and the sport's fanbase. In 2008, NASCAR driver Dale Earnhardt Jr. guest-starred in an episode titled "Poor and Stupid," where he is depicted as a "brain-dead" redneck. Additionally, the series has used NASCAR as a plot point in several other episodes, including "Red Man's Greed" and "It's a Jersey Thing."
