Scene: Lunchtime in a fellow teacher's classroom. Dr. Chemistry is working on chem equations with a student, and I'm sitting nearby eating my lunch. Another student walks past the open door of the classroom; Dr. Chemistry waves at the student, and the student hurriedly continues past without acknowledging the wave.
Dr. C: He looked scared. I wonder why he looked so scared.
Student: Because you're terrifying.
Dr. C: I don't see why everyone thinks I'm so scary. I haven't killed or eaten anyone that they know of.
[... Long silent pause as the student stares, somewhat disconcerted, at Dr. Chemistry. I, meanwhile, am merely thoughtful. After a moment...]
Me: Why would you eat them?
Dr. C: Because I'm hungry. Pretty much all the time.
Me: Okay, but I mean, you really ought to be able to find something tastier to eat than the rotting carcasses of your victims, right?
Dr. C: Humans don't taste that bad, actually.
Me: Yeah, but still. I mean, there must be something better.
Student: See, it's exchanges like this that make you two pretty much the scariest teachers EVER.
Don't worry, though: I make up for being scary by also being well-dressed...
Scary? Me? Nah...
