Roses and Teeth for Ludwig Wittgenstein Lyrics

"A new born child has no teeth."
"A goose has no teeth."
"A rose has no teeth."
This last at any rateâ "
one would like to sayâ "
is obviously true!
It is even surer that a goose has none.
And yet it is none so clear.
For where should a rose's teeth have been?
The goose has none in its jaw. Matmos - Roses and Teeth for Ludwig Wittgenstein - http://motolyrics.com/matmos/roses-and-teeth-for-ludwig-wittgenstein-lyrics.html
And neither, of course, has it any in its wings;
but no one means that when he says it has no teeth.
Why, suppose one were to say:
the cow chews its food and then dungs the rose with it,
so the rose has teeth in the mouth of a beast.
This would not be absurd,
because one has no notion in advance where to look for teeth in a rose.
(Connexion with "pain in someone else's body".)
