What is the correct answer to this famous tongue-twister?

If Peter Piper picked a peck of pickled peppers, how many pickled peppers did Peter Piper pick?

HINT:
It has nothing to do with how many peppers it takes to fill a peck (which is a quarter of a bushel).

Answer:

NONE ............ Peter Piper couldn't have picked any pickled peppers because peppers are picked unpickled.
