You want a piece of me?

Professor P describes the exam:
Jack: “What makes a good exam answer? Like what are you looking for?”
Professor P: “Well, one of the questions is going to ask for a piece of you. You have to be original and creative…”
Jill: “A piece of me? Can I just attach a hair or something?”
Professor P: “Uh, I was thinking of an intellectual piece.”
