Herman the cow was a purple cow. All the other cows would not let him play. He made purple milk. People in the store thought the milk would be nasty. One day a family had no milk and only purple milk was left, so they bought the purple cow milk. They thought it was very good. It was in the newspaper. It was popular. The purple cow was proud of himself, so the white cows let him play with them. They played happily.
