What is the true meaning behind 'Peter Piper'?

The true meaning of Peter Piper is that he was a man that worked as a pickle pepper picker. He couldn't add or subtract so when pay day came his boss shorted him of his pay. So he would do extra work for no extra pay or full pay for that matter. Because his boss shorted him he was a very poor man. This is the meaning behind it, but it is just a made up riddle that never really occured.
