'Topsy' (Season Three)
'It's a favorite because of the music — and in particular, because it was Gene's music. We realized, maybe this kid can really put a piece of music together; maybe he's sort of a savant in a way. Why not? So we got this idea that he was going to write for Fischoeder and Gail (voiced by Kevin Kline and Megan Mulally) to sing. I love that in the middle of it, he says maybe we're going to get some kids from band class, or a couple of choir kids, and all of a sudden he's pulling in his backing instruments. It was so fun for me, as a wanna-be musician, to fool around with that stuff. That kind of pointed the way for where we could go with the musical aspects of the show. The Season Five premiere is a full-blown, wall-to-wall musical episode."
