I had one that sounds a lot like this, but for anthropology; ex-CIA, inspiring, making fun of people for sleeping. He also smoked a fragrant tobacco pipe. He was so unexpected, too, because I was attending a community college at the time and didn't have to too many great professors. His class is one of the few that I remember from that time, and it inspired me to endeavor to live my life to the fullest. Maybe ex-CIA agents are just awesome people.
