One of my substitute teachers in high school was the older brother of a guy I knew + one of the school counselors. He subbed my American Government class for a whole week and BOY did I enjoy that week in there. He also subbed my economics class a couple of times the following semester.
As for college, the only professor I've found attractive was my Political Science teacher I had last semester. He was like part white/part South American and part Middle Eastern. He was from New York but lived in South America for awhile so his accent was very unique and interesting

. He was also a very easy professor so I got an A in there which makes him even better.
