I have eaten
the planet
that was in
the icebox

and which
you were probably
saving
for your grandchildren

Forgive me
it was delicious
so sweet
and so profitable

@JuliusGoat
I had to do a Google search for the author; weird how I can recognise lines from a poem or song after decades of not seeing or hearing them, while I have no memory at all for names.
Anyway, yes: William Carlos Williams.

@Jantar @JuliusGoat Looks like he wrote the original poem:

This Is Just To Say
By William Carlos Williams

I have eaten
the plums
that were in
the icebox

and which
you were probably
saving
for breakfast

Forgive me
they were delicious
so sweet
and so cold
