Is anyone aware of a book that tackles humor as a subject? The best one I could find is humor's role in forming persuasive arguments (http://www.pearsonhighered.com/educator/academic/product/0,3110,0321434900,00.html). I'm just looking for one that might tackle it on a philosophical, psychological, or another similar point of view. So far, I haven't found any books like "Intro to Humor" or something. I know there are things being done to research humor (my psychology professor has done research on humor's effect on personality). There has to be some kind of book out there on different aspects of humor or theories of it.
