In one of my early semesters as a professor I entered my Friday, *8 am* Marketing class to find - an entire room full of students! I was ecstatic - until I realized they were there to get feedback on their most recent exam, which of course I didn't have graded yet. I joyfully exclaimed that there'd be no grades today but there would be more on marketing.
A few hours later, another professor approached me, his arm outstretched to shake my hand. I looked at him, puzzled. He said - I just heard the students call you "the marketing nazi." He was all grins and the moniker has since felt like the coming together of learning and fun.
