The story of this goes:
I was minding my own business ((apart from raiding Hobbit holes)) and I stumbled upon a house that took my fancy. I went in it and asked a hobbit how it was going. They replied saying: "The Sackville-Bagginses came for lunch yesterday. Now I can't find any of my plates, nor my mugs..." ((They still had both in their storage room though)). I then went to go to the larder to steal all their food, and lo and behold, a child was going to be cannibalized...
