(I’m sitting in a large classroom waiting for a third-year lecture on evolution to begin. Behind me I hear two students chatting.)

Man: “So I finally broke down and bought the textbook.”

Woman: “Oh?”

Man: “Yeah, but I made the mistake of leaving it lying around my parents’ place. My mom got all defensive seeing it, talking about how evolution wasn’t real. Then she asked me why I was taking the course.”

Woman: “What did you tell her?”

Man: *sarcastically* “‘It’s just for interest! It’s not like its one of the uniting principles of my majoring subject or anything.’ I think she bought it.”
