Why He Rocks

 * 1) He is a great substitute teacher since he has knowledge on many subjects.
 * 2) He cares deeply about his students, even rejecting romantic relationships.
 * 3) He helps Lisa reconcile with his father, and cheers her up when she learns he is leaving.
 * 4) He is not only a great teacher, but a great person, as he is shown to have talked to some of the people in his temporary apartment.
 * 5) He even visits Lisa's house in a later episode (The Season 25 episode, "The Kid is All Right", to be precise) and puts hot butter on her vegetables, showing that he did not forget Lisa.
