Cringey things that math teachers do

I hate all of these things:

• They make cringey jokes
• They overact, usually trying to make math seem less formal, or "cool."
• They make cringey songs about math
• They make religious statements, often at the beginning or end of their videos. Here's an example of a religious statement at the beginning of a video, and here's an example of a religious statement at the end of a video.
• They are teachers of critical thinking, and yet, hold ridiculous views, such as a belief in astrology, or a belief in a 9/11 conspiracy theory.
