Lyrics: Jack and Jill
Jack and Jill went up the hill,
To fetch a pail of water;
Jack fell down, and broke his crown,
And Jill came tumbling after.
Then up Jack got and off did trot,
As fast as he could caper,
To old Dame Dob, who patched his nob
With vinegar and brown paper.
Traditionally a nonsense verse in the form of a game, particularly as the couple go up a hill to find water, which is often incorrectly thought to be only found at the bottom of hills. Vinegar and brown paper were a home cure used as a method to draw out bruises on the body.
Jack is the most common name used in English-language nursery rhymes while Jill or Gill had come to mean a young girl or a sweetheart by the end of the Middle Ages. (source)
