Yeah, jsut go talk to the dean. Remember, be polite, and don't speak for anyone else in the class. Just say "Professor X has done this, this, and this on numerous occasions and it is hindering my ability to get to work on time." Any dean worth their salt will know in about two seconds that your professor is being a total dildo.
Good luck
