There Once Were No Men Who Ate Prunes

There once were no men who ate prunes

They feasted on dates in the dunes

...

...

Were it not for the gnashins and chewins

— Karl Jones (for Steven Brust)

Origin

Steve posted a limerick about plums.

I challenged him to write a limerick about prunes; he refused.

It seems that I can't rely on other people to do for me the work I should be doing for myself, so I did it for myself and dedicated it to them.

Thus does symmetry assert itself.
