We all have some hilarious class stories, but this one takes the cake.
High school years I had a calculus teacher who hated anyone with an mp3 player, whether or not it was in use. She was known to confiscate them even if earbuds were hanging out of a backpack. One day my friend comes into class sits down and puts on these huge obnoxious headphones. Teacher gets pissed, starts screaming at him, and asks him to open his bag so she could confiscate the contraband. Well, he unzips his bag to reveal that the headphones were plugged into a small pumpkin. She looks confused and walks back to her desk carrying the pumpkin with her.
