When Rose is looking for a live-in superintendent, Manny suggests his father, knowing that the Super's family will live with a 50% decrease in rent. When his family moves in, they later find out that he is also the Superintendent, but Alfonso has no skills in that area. Instead, he would rather play concert violin in a symphony. When a try-out conflicts with his job as Super, he decides to complete his job as Super, but Rose allows him one more day to complete his job so he can try out for the Orchestra. He doesn't make it, but vows to put his all into being the Super. (thetvdb.com)
