If you (like myself) like your professor to be organized and to present the class material in an efficient way then DONT take any classes with Tangherlini! Sure he is fun and interesting, but that doesnt really mean all that much when you are trying to figure out how to write a 10 page paper when nothing has been covered! Trust me, it is not worth it, the class is not as easy as people say.
When you first get into this class, it seems really kick back and relaxed... but its not. Sure, there isnt too much work to do, but the grading is very hard on the midterms and essays. I asked the TA for help on my essay and we worked on it for a while, and even after all his help I ended up with a B or B- on it. His lectures aren't that bad though cuz he uses powerpoint and he puts it online, so that helps.
Most hilarious professor I have ever had. There was not one lecture where he didn't have the class cracking up. The man makes you want to go to lecture, and he is thoroughly entertaining as well as educational and makes his lectures accessible to all. Truly a genius. Also very easy. My only complaint is that he assigned an unrealistic amount of reading each week.
