The Günter-Grass-Haus published this poem from his work "Fundsachen für Nichtleser"
Mit einem Sack Nüsse
will ich begraben sein
und mit neuesten Zähnen.
Wenn es dann kracht,
wo ich liege,
kann vermutet werden:
Er ist das,
immer noch er.
I don't think it's available in English, and I'll add my own translation here. I hope that's not too presumptuous. I've done some translation, but translating poetry is difficult. With a bag of nuts
I'd like to be buried
and with the freshest of teeth.
When there is gnashing
where I lie,
one can surmise:
He's at it,
still he.
