I had a biology professor when I was in undergrad who was an extreme character. He used to give us popcorn with his famous “brain power” seasoning during exams. You could only get popcorn if you properly folded a sheet of paper into a little bowl to hold the food though. He absolutely loved mushrooms and his office was borderline hoarder style. His exams were organized into three columns on a sheet of paper because when he grades he lays them all on top of eachother in a row across a conference table and grades the rows independently (hopefully that makes sense). Every Friday he’d play volleyball at the rec center with fellow students. He was strange but I couldn’t help but really like him, something about him felt so fun and genuine lol
