A new teacher comes to class to teach a lesson on a complicated math theorem. The class is waiting completely nude and catches her off guard. She takes off her clothes before the beginning of her lesson. During the lesson, the students put their clothes back on and take away her clothes, as she is concentrated solely on the theorem. Upon finishing, she is embarrassed that they are clothed and she is left naked, but there is now someone at the door. The class ask the unknown to come in, and they find a naked teacher but clothed students. Inspired by a mathematical rhetoric.
