i know right
i would seriously do the same thing if i was faced with that situation.
What I'd yell:
"Dammit guys, our teacher works her ass off, she stays up late each night to plan lessons for us. She wakes up at like 3:30 to get ready for the day, and all you guys do is treat her like stuff. So shut the hell up and listen."
