He has a very dry sense of humor that only certain students can understand. If you understand the humor, you will really enjoy the class; if you don't, it will be a long semester. Overall, he's ok.
He is a "teacher" that makes students hate school. He seems that he hates his own life so much that the only remedy for him is to try and make students loathe their own while at school.
Stephenson is an awful teacher; the only thing I remember about his class is that he told us that smoking is good for the economy. What teacher would tell a class of sophomores that smoking is good?
