Line from a poem: Odd as a poet.

I recently wrote a piece (of poetry) with the simile "odd as a poet" somewhere in it. The problem is I'm not sure if it's actually originally by another writer.

I have googled the term, and there is nothing coming up, but I still have this bad feeling that my mind has simply remembered it from another person's work. If so, I obviously don't want to retain it. I have a feeling it might have appeared in a Paddy Kavanagh poem.

Can anyone help, do you know of its use elsewhere?

Many thanks
