"Peter Percival Patterson's Pet Pig Porky"

I was thinking about "Peter Percival Patterson's Pet Pig Porky" recently, and I realized that there are a couple significant rhetorical effects.  Of course, there are the alliterative Ps throughout, and there are also two rhetorical catalogues ("pizza pie, pumpkin pie, pineapple pie, pizza pie, mince tarts" and "pie for breakfast, pie for lunch, pie in the afternoon, and pie before he went to bed").  Both of these features provide a sense of amount (the "so much pie" mentioned near the end).
