"A crow was sitting on a branch eating my lunch one day," said Crow.  "Fox stopped by and said, 'A charming bird like you must have a lovely voice.'  The crow opened its bill to sing and dropped a fine piece of cheese.  Fox walked away with the crow's cheese and had the nerve to tell the crow that the crow sings out of tune."  Rabbit said, "Rabbit still has cramps from the sour grapes fox traded for rabbit's sweet, ripe grapes.  Fox told rabbit that sour grapes are full of vitamin C."
