Ever had creepy University professors?

Honest question, people who were inappropriate, or you suspected were inappropriate, but never did anything about the situation?

I went to office hours of this professor this one time, and he was kind of chatting me up when I was doing my work, (on calculations), he was doing something then he was like 'Ah, it doesn't look good doing this in front of a lady," (he was rolling up the cup or something like that.

I'm not sure what he meant but I smiled politely, and went away.

Looking back I wonder how many Profs in University were secretly creeps in disguise, (I know that's a huge accusation, but I'm sure there were/are men working in Professor positions, who are out to prey at young women)
