Ms. Kunkle
Karen Kunkle (Erin Matthews) is a very strict Biology teacher of Jackson and Miley Stewart, Lilly Truscott, and Oliver Oken.
She was first shown in the episode, People Who Use People. In that episode, Jackson tried to get her to marry his father, Robby Ray Stewart. That didn't turn out well. Next, she was shown in the episode, Get Down, Study-udy-udy, in which she kept scolding Miley for doing "The Bone Dance", but at the end she gave her an "A" for it. The next episode she was seen in was Sleepwalk This Way. In this episode, Miley Stewart falls asleep and starts insulting "Skunkle", as they call her. She gets Lilly Truscott and Oliver Oken in trouble, too.
Her final appearance was in Hannah Montana To The Principal's Office.
