What is the strangest nursery rhyme?

Answer 1

The question you ask does not have an answer. The reason for this is because your question is a matter of opinion. A nursery rhyme that seems strange to you might make the most of sense to someone else.

Answer 2

One example of a strange nursery rhyme is "There Was an Old Woman Who Lived in a Shoe," which tells the story of an old woman who lives in a shoe with her many children. The concept of living in a shoe is unconventional and whimsical, making it stand out as an unusual nursery rhyme.
