No, this is not a School of Rock dream. My Calculus teacher was busy telling us to get ready to take a calculator quiz, so everyone's groaning and everything you do before a quiz. She passed out the papers and said "begin" and we all started. When she said begin, the screen turned on to reveal a concert backdrop. She climbed on top of a desk and got out a sparkling red electric guitar. A speaker came form nowhere and she started jamming. Some kid got the courage to ask what she was doing. She responded: "Shredding papers" All the papers ripped and tore, leaving all of us in shock and two people screaming.
