Cool Teacher: Admit it, you'd love to have him as your teacher.
Deal with the Devil: To get Li'l D out of his. Then he acts so bad, explaining that he had no soul in his work, and thus gets his soul back and saves both of them from the devil.
I Just Want to Be Normal: To an extent: He goes back to teaching because he got tired of life as a music superstar and almost quits when a hoard of celebrities try to teach at the school.
Noodle Incident: Used as a joke twice. First to show how the class always gets into situations, and a second time to saw just how naughty he has that year.
Hidden Depths: Her house looks like something from Snow White and the only chores she's supposed to do is clean her room and do the lawn. The lawn is surprisingly clean and neat.
Vocal Evolution: The early episodes gave him a higher, faster voice, and he appears to have an accent. In later episodes, his voice is lower, slower, and has lost its accent. Possibly Zig Zagged, as even later episodes have him switch between the two, or use a voice that sounds like the first two put together.
Edward "Eddie" Phillip James Lawrence III
Fiction 500: He's somehow rich enough to have ten fingers (as Philly Phil notes when he sees his own eight).
