Apparently, one suggestion as to the origins of this song is related to The Metropolitan Polce.

"Like many folk songs the origin of "Ten Green Bottles" is lost to antiquity, it was believed to be of English, more specifically of Yorkshire origin, although one suggestion is that greenbottles refers to officers of the Metropolitan Police, apparently underworld jargon for the new force founded by Act of Parliament in 1829. This could explain why the bottles were said to be hanging on the wall rather than sitting on it. "

How appropriate.

And here are the lyrics, just in case you really need to know. -Joe Offer-

TEN GREEN BOTTLES

Ten green bottles hanging on the wall
Ten green bottles hanging on the wall
And if one green bottle should accidentally fall
There'd be nine green bottles hanging on the wall
