Okay, so that teacher is now afraid of me.
I found a picture (of Hanson) that I was originally gonna cut out and tape in my locker, but it ended up just staying in my backpack that I took out, and wrote a letter to him.
I even included 5 of my favorite songs from each cd (minus MONA, and the live cds) for him to listen to.
He was really surprised that they looked the way they did.
But, the plus is, he told all his classes that he was wrong, they weren't a fad. They are still around. My mission is accomplished.
