Those are the ones I like, too. But I sometimes appreciate the funny ones, especially in required classes in which I don't particularly care whether I learn anything or not (though there are some funny professors who also know their stuff and can teach it). I remember being at Baylor in 1992 and one of my Tax Accounting professors wore a Clinton/Gore t-shirt to class. I thought the class was going to revolt against him. Personally, I've had very few truly liberal professors, but I've gone to schools that would probably skew conservative and took mostly business or business-related (Advertising) classes. I did have a political science professor who really did play devil's advocate well, as well as bringing up points in an effort to get people not only to think, but to think things through. In the end, though, I could not have told you what he really believed personally. But I felt like he did impart the importance of thinking for one's self. (And I thought it was nice that he didn't label any of the views one way or another. For example, if he were talking about pollution in the Mississippi River, he didn't say that the conservative viewpoint would promote this or that and the liberal viewpoint would promote this or that. We talked through the issues and never tried to put a label on the opinions).
