Answer and go in to work.

It's your boss, like you knew it would be. Your professor is sick and you will have to teach the class on your own. You get up and without putting any clothes on, you go to work. Once there, you strut naked into your class and tell them you are going to teach sex ed today and if anyone has any issues, they can leave. Only girls leave the class, but to your surprise, a few stayed behind.
