Major Rule
One of the most important rules in filmmaking is to never breach the fourth wall, which means not looking directly at the camera or speaking to the audience. This utterly removes your feeling of reality and reminds you that you are watching a movie! However, this bizarre film ignored conventional conventions, and Bart not only randomly hugged himself, but also turned directly to the camera and addressed the audience. Absolutely hilarious.
Removed on Purpose
Despite her doubts during the audition, Kahn was quite excited to play Shtupp. In fact, Lucille Ball accused her of intentionally giving a horrible performance in her previous film Mame so that she would be fired! She was sacked, and the next day she started working on Blazing Saddles. Because she was dismissed rather than quit, she received pay for both films.
