I think there have been a few threads or discussions along this line in the past, but since new classes are added every year, I thought it might be fun to revisit given the dearth of non-OT news.
Here are mine (which all have "are easy" as a pre-req):
1) Psychology and Spiritual Development - One word - self-graded. I gave myself an A since I was an awesome student. Also, Richard Mann was super cool and had some great stories about the 60's.
2) Greek Mythology - A surprisingly useful class for life, especially if you like to read. Professor Verhoogt is funny and the class was pretty easy.
3) The History of Witchcraft - Another gem in the Classic Civ department, which seems to have the highest ratio of easy classes of any department at the U. Don't remember the name of the professor, but he looks like Barack Obama (before he became President) and was a great lecturer. The material was fascinating.
What are yours?
