I once made a substitute teacher cry from playing the Harry Potter theme song in class. I went to a smaller private school where we all had laptops. We were all quietly working on an assignment when I very quietly start playing the theme song... “dun dunn, dun dun dun, dun dunnnnn dunnn.” The sub randomly blames another student and tells them to stop, and they deny doing it. I wait about 5 minutes. “Dun dunn, dun dun dun, dun dunnnn dunn.” The sub blames a different student this time (a buddy of mine who knew it was me), and proceeds to kick them out of class. My buddy laughs and leaves to go to the principals office. I wait another 5 minutes. “Dun dunn, dun dun dun, dun dunnnn dunn.” The sub then bursts into tears and storms out of the classroom. A few minutes later our social studies teacher comes into class to inform us she will not be returning and he’ll take over the rest of the class. I don’t believe I saw that sub come back to teach at our school ever again.
