7th grade math teacher heard heard some 9th graders saying that he propably never gets any. Proceeded to explain to his 7th class that he fucks his 10 years younger wife a lot and that they are in an open polyamorous relationship.
My sister once had a teacher tell the class that they had to write a paper on a “famous Egyptian. You know, like Socrates”
My sister was given in school suspension for disrupting class with her laughter. She appealed it, and in the appeal meeting with our mom and the principal, the teacher insisted that Socrates was Egyptian.
The suspension was canceled, my sister didn’t have to write the paper, and AFAIK that teacher is still working at the same school as a teacher.
