The CBS TV show, The Big Bang Theory teaches financial responsibility and discipline.
In Season 2 Episode 14, Penny needs money to pay rent and Sheldon lends her money. Sheldon lives below his means and saves up for the rainy days. In contrast, Penny lives “hand to mouth,” or paycheck by paycheck. She sometimes overspends and is often behind in bills.
Penny could not make rent and tells the story to Sheldon. Sheldon generously and gladly offers Penny his “secret” stash of money. He spends only what he needs and saves the extra money.
The lesson that can be learned here is that if we practice financial responsibility, i.e. spending less than we earn and have the discipline to control our spending we can avoid financial disasters like not making rent such as Penny does.
