That’s an interesting question. Let me ask you, what if “picked” means “selected” and a “peck” is a prepackaged basket-sized container of pickled peppers?
If one looks at it in that context, then Peter Piper went to the store and selected a container of pickled peppers.
The real question then becomes one of morality: Did Peter Piper pay the proprietor for the peck of pickled peppers or did Peter Piper pinch the peck of pickled peppers?
Under my painless 999 Plan, Peter Piper palpably paid the proprietor for the peck of pickled peppers without having to parley a payment plan with the proprietor for a portative peck of pickled peppers.
:p
