How Does He Come Up With That?

I don't know how they keep making every song, every album, totally differet than the last one. I've always loved this lyric of theirs - it's her green plastic watering can for her fake chinese rubber plant in the fake plastic earth she bought from a rubber man in a town full of rubber plans to get rid of itself. And i just want to say, how does he come up with that? How do you make such great lyrics and then not articulate them in the song or on stage? Such that people can hear them verbatim and appreciate their specificity. You know, like people who write poetry, they really love that they're writing poetry and you can read it
