I Have Been to Market, My Lady, My Lady

I have been to market, my lady, my lady;
Then you've not been to the fair, says pussy, says pussy;
I bought me a rabbit, my lady, my lady;
Then you did not buy a hare, says pussy, says pussy;
I roasted it for dinner, my lady, my lady;
Then you did not boil it, says pussy, says pussy;
And then I ate it, my lady, my lady;
And I'll eat you, says pussy, says pussy.

This ditty has been described as "a conversation between a mouse and a cat"... though if I were the cat, I'm not sure I'd mess with a mouse that eat rabbits! The earliest this rhyme appears in a collection is 1869.
