When I was younger my first job at the University was teaching a course on sex education. I wasn't exactly sure how I was going to tell my wife, so I just told her that I was teaching a class on sailing. She thought it was strange because I had very little experience sailing, but I told her the University really needed someone and they had picked me.

Everything was going smoothly until one day, towards the end of the semester, we were at the mall and ran into one of my students. I introduced them and he told her what a great teacher I was. She said, "I don't know how he can be such a good teacher. He's only done it twice. The first time he got sick and the second time he lost his hat!"
