The sheep with the crumpled horn - 

 with apologies to 'The House that Jack Built'

This is the farmer sowing his corn

That kept the cock that crowed in the morn

That woke the priest all shaven and shorn

That married the man all tattered and torn

That kissed the maiden all forlorn

That milked the cow with the crumpled horn

That tossed the dog that worried the cat

That killed the rat that ate the malt

That lay in the house that Jack built.
