Are you joking, hands down Professor Christopher Hanna is the greatest professor the world over! There were students who once challenged his knowledge of a particular taxation issue. They asked a very detailed question. He turned to them and within 60 seconds gave them the answer — they were shocked, the class was in total shock. The answer was in a statute’s subsection. He recited the section number and all of its subsections… it was truly a crazy moment! Great teacher!
