One of my favorite math-related scenes in The Simpsons is where Prof. Frink is standing on stage in front of a group of scientists and not getting attention.

Prof. Frink: "Looking for some order. Some order please with the eyes forward and the hands neatly folded."

(Audience not paying attention.)

Prof. Frink: "Hrm..."

Prof. Frink: "Pi is exactly three!"

(Collective gasp from the audience. Prof. Frink now has their attention.)

Edit: Went looking for part of the quote which I couldn't catch, found a book which seems interesting. Simon Singh, 2013. The Simpsons and Their Mathematical Secrets [1]. Singh is also known for his 1997 book Fermat's Enigma [2] and his 1999 book The Code Book [3]. The former of the books I've heard is interesting and the latter of which I enjoyed very much back when I read it.
