In life, we are taught that there is no such thing as a stupid question. But when you're a teacher, you know that some questions are just straight-up dumb. These teachers and fellow students shared the stupidest questions they've ever heard, and some of them will leave you scratching your head.
Had a student ask me "What are those pyramid-shaped things in Egypt called?"
Never seen a class laugh that hard before.
I once projected a picture of the Earth onto the front whiteboard. A student asked, "How do astronauts stand on a planet like that?"
Edit: Was an 8th-grade student, being totally serious, not under any noticeable influence of illegal substances.
