What songs {folk songs or otherwise} or children's playground rhymes can you think of that include a reference to #9?

What, if anything, does #9 mean, and why does it seem to occur so often in songs & rhymes?

I'll start the ball rolling with some examples from my memory and some examples I've collected on Mudcat, on my website Cocojams, and elsewhere.

Please join in the fun & games by sharing examples of & comments about songs and rhymes that mention the number 9!*

For the sake of folkloric documentation, if you post any examples of children's playground rhymes, please include demographical information-particularly where {city, state in the US, and city, country outside the USA} you remember chanting that rhyme or when you first heard it chanted. Also, please include performance information such as whether this was/is a counting out rhyme, a ball bouncing/jump rope {skip rope} rhyme, or a handclap rhyme {hand game} etc.

Thanks, in advance, for your participation in this thread!

* For the record, I'm still working on a book about English children's rhymes, and I may be interested in including any examples of those rhymes that are posted on this thread.
