Don't let that horse

Don't let that horse
         eat that violin
cried Chagall's mother

             But he
        kept right on
             painting

And became famous

And kept on painting
                  The Horse With Violin In Mouth
And when he finally finished it
he jumped up upon the horse
                 and rode away
        waving the violin

And then with a low bow gave it
to the first naked nude he ran across

And there were no strings
                 attached

Lawrence Ferlinghetti
