I just saw the most hilarious thing

I'm sitting here watching a medical ethics lecture, no idea what he's talking about, and he's holding a recorder and talking into it to record himself. One of the students sneaks up behind him, points at the speaker with a confused look on her face then shrugs and walks away. Then another student does the exact same thing. The professor keeps going all confused about why everyone keeps pointing at his recorder. Eventually he calls the people in the back of the auditorium the "juiciest specimens."
