Alright, maybe I'm still testy with my 3rd period class

"Who is William Bradford?"

"Actually, you know what? I don't think I'll be answering any more dumb questions. So, I need complete silence and if there's an answer to something you can't find right in front of your face on the chalkboard or in the book, and it's something that hasn't been asked in the last 60 seconds, then I'll be happy to answer it. Otherwise, you're on your own, and if you decide to talk without given expressed permission, I'll deduct ten points off your test."
