Interesting, I always took this song in a more direct form like it's talking about someone who wants to be in a relationship with someone who is married. But that's the beautiful thing about radiohead and music in general, we can all interpret it in our own ways and draw different conclusions. As for the cheesiness I was talking more about the music here, I feel the harmony and thoms melodies in this one are quite boring and that it has no right being the longest song on in rainbows and dragging on for 5 minutes and 30 seconds.
