By the Prisoner's Dilemma

I'm baaaaaaaaack! Did you miss me? Oh. What? I'm everywhere? No way! I'm glad you're thinking of me. 

You really thought you had seen the last of me? Joke's on you! Fat chance. Ec 10 was just the beginning, baby. 

You dare try to avoid me by taking a science class? Oh honey, I'm in Primate Social Behavior. SLS 20? I'm there. Ec 1661? I'm there, too. Your Aesthetic and Interpretative Understanding class on the Bible? Bitch, please. You think that God didn't ever wonder if the devil had incentive to cheat?
