This message actually contains the complete versions of both nursery rhymes: Little Jack Horner and Jack and Jill:
Little Jack Horner
Little Jack Horner sat in the corner
Eating his Christmas pie.
He put in his thumb and pulled out a plum
And said, "What a good boy am I."
Jack and Jill
Jack and Jill went up the hill
To fetch a pail of water.
Jack came down and broke his crown
And Jill came tumbling after.
