During our first lab in my Honors Chem class, my teacher asked me to flip a switch to turn on the fans. There was only one there, but as I flipped it he looked terrified and shouted, "No!! Not that one!!" I turned it off and jumped backwards, scared I just blew up the school, and the entire class turned to stare at me. After a second he added, "No I'm totally kidding. That's right," and continued doing his work normally. Hello, favorite teacher. MLIA.
