So you want to question me about your grades and ask for extra credit? I've been a professor for a long time and I've never been so insulted by a student. Well, I guess there's one way you might be able to get on my good side - but I don't think you're going to like it! Here, let me demonstrate with some food what's about to happen when I toss your tiny little body down my throat. What's that? You're scared and want to go home? Great idea, since my mouth is your home now!
