As of a few minutes ago, some champion of an anonymous reviewer informed me of the fact that there's a third verse to the song.

Thank you, excellent person. You have made my life a hell of a lot easier by giving me another verse to work with. Because as it turns out, fics of fixed length are hellishly hard.

This as yet unheard of (at least by me) verse goes as follows:

She wears a flannel nightie in the summer when it's hot

And she wears her pink pyjamas in the winter when it's not

And sometimes in the springtime and sometimes in the fall

She lays between the lily-white sheets with nothing on at all.
