I'm almost sure this rhyme came from a historical British political incident. It is kind of "in code" for an attempt to over throw the queen and the consequences to the conspirators:
3, 6, 9, the goose drank wine= One of them was poisoned
the monkey chewed tobacco on a street called Line= where they were supposed to meet.
The line broke= the conspiracy was discovered.
The monkey got choked= hanged
And they all went to heaven on a little row boat= deported to Australia.
I'm sure I've heard this explanation some where- Anybody can provide details? Jay
