Nursery-rhymes/generate-nursery-rhymes ? reverse-engineered prompt

Build me a simple Python script that generates random nursery rhyme lyrics by mixing and matching phrases from famous nursery rhymes. I want to run it from the command line and have it print a new silly rhyme each time, with different combinations every run.

Please keep it lightweight and easy to edit, so I can add or remove phrases from the built in list later. It should use Python’s standard library only, no extra installs needed. If it helps, make the script easy to understand for someone who just wants to tinker with the phrase list and see fun results right away.

If you need to check anything, look up current Python docs online, but keep the whole thing simple and self contained. A small README note on how to run it and how to customize the phrase list would be great too.
