Dr. Horribles
Dr. Horribles, a strange and freaky doctor who couldn't sing properly, created a blog to teach others how to sing but ended up laughing maniacally at his own tutorials.
He is jocular and goofy, hails from a small, eccentric town, was once a failing music student, enjoys collecting odd medical gadgets, dislikes animals (except for sharks), attended a mysterious medical conference in Transylvania, and graduated at the bottom of his class with a degree in music therapy.
