I would like to respond to this post made quite literally before I was born, by saying that if you were to put double spaces between Pig and and, and and and, and and and, and and and, and and and, and and and, and and and, and and and, and and and, and and and, and and and, and and and, and and and, and and and, and and and, and and and, and and and, and and and, and and and, and and and and and and Whistle, I think your sentence would have been much more clear.
Because you're putting a comma between an instance of the word and (noun) and another word and (noun). IE between an and and an and. Just like you could say "Put a comma between a but and a but. Each time you used but in that sentence it was a noun.
