A repeating chase rhyme about a thief called Taffy who keeps raiding the narrator's larder, ending with a bone thrown at his head. One of the oldest and most reprinted nursery rhymes, though its Welsh-thief joke has not aged well.
From Mother Goose / Nursery Rhymes (traditional). See the whole collection.
Taffy was a Welshman, Taffy was a thief,
Taffy came to my house and stole a piece of beef;
I went to Taffy's house, Taffy was not home;
Taffy came to my house and stole a marrow-bone.
I went to Taffy's house, Taffy was not in;
Taffy came to my house and stole a silver pin;
I went to Taffy's house, Taffy was in bed,
I took up the marrow-bone and flung it at his head.
