I liked this one a lot! It was the first episode I ever saw, which made me think the show was good, until I saw the other episodes. But anyway, this one was a very good episode. Amber (the school bully) is going on Singing With The Stars, and is going to sing with Hannah Montana. Miley uses this as a chance to get back at Amber, who has constantly been horrible to her. After hearing her sing in the bathrooms, she finds out that she's tone deaf and stands no chance, but they then find out that was her stupid "sidekick" or even "slave" Ashley, and Amber is AMAZING. Hannah is going to get her back, until she finds out a bit more about Amber, and decides not to, which all goes wrong when she ends up on stage.
What I hated about this episode was the subplot. The only bit I laughed at was the speaker bit, when the dog started breaking the wires or something. Other than that, good episode.
