I always find professors that have a sense of humor and who are relatively light-hearted pretty fantastic. For instance, my Intro to Lit professor just throws out random stuff every single day that is just so randomly funny. But, I have an off-the-wall sense of humor, so it might be just me. Oh well. Today, he somehow got on the subject of Tina Turner, and he said, "Tina Turner andI have a win-win relationship."
Then, "You shouldn't do this. Do not play with mercury."
If that's all I take with me once I graduate college, I'd say that was money well spent.
