"Definition of Good" by They Might Be Giants

We got the kiddo the new kids album by They Might Be Giants for Christmas, so we've been listening to it around the house with him.  This song keeps getting stuck in my head.  I won't make any recommendations about the music part of this song (which is, in my opinion, totally solid but not exemplary) but the lyrics just hit it out of the park for me.  I think they capture really perfectly a particular feeling of intimacy shared by a family (different from couples' intimacy).  And while this song is on a kids album, to me it's parents writing a song for other parents; it winks over the kids' heads in a way that is not disrespectful of the children.
