The top 22 mistakes in TV shows The Big Bang Theory

More name mix-ups occur early on in the long-running US sitcom. The aspiring actress Penny, played by Kaley Cuoco, refers to her dad as “Bob”, but once he’s introduced on the show, he is called “Wyatt”. Also there is a plot mistake regarding the broken elevator in the apartment building. When they lug the time machine up the stairs in season one, Leonard explains to Howard that the elevator has been broken for two years. But Howard should know this considering he was there when Leonard blew it up. This is revealed during a flash back in a later episode, where it also states that the event took place five years ago, not two.
