I find it funny when professors have to advertise their classes to get people to take it. And I mean literally advertise it by putting up ghetto flyers all over the place, like the way they would if they were trying to sell their coffee table or something. Are you interested in PRIME NUMBERS???? Then sign up for M372J for a FUN and EXCITING experience!!!!!! Times New Roman, WordArt, a slew of exclamation marks, and sometimes a random clipart of an electron or the like. Very middle-school-science-report-esque. I am easily amused. :)
