Babooshka grammar

[Michael Mendelson <mendel@cs.uiuc.edu>]

I was listening to the Whole Story today and in the song Babooshka,
I thought I heard Kate say

		"She couldn't have made a worst move..."
					  ----^

which is grammatically incorrect (it should be worsE).  So I checked
the lyrics I have from the lyrics server, and (although I know there
are some mistakes in there) they said "worse."

I listened to the song again and indeed Kate utters a very pronounced
worsT.  Has anyone else noticed this?  Is Kate intentionally erring?
Or am I missing something subtle in the lyrics?  I suppose the sentence
could mean that "She was incapable of making a WORST move," but from
the context, this does not appear to be the intended meaning.
