...and you takes your chances?

I used this phrase today, and someone asked me where it came from. Help!

Googling found this: Punch, a English humorous weekly periodical, 1841-1992. Quotations:
You pays your money and you takes your choice. (vol.10, p.17, 1846)

Another source is in agreement with the above -- it is Cockney speech recorded in Punch in 1846. From Dictionary of Catch Phrases: American and British, from the Sixteenth Century to the Present Day by Eric Partridge, updated and edited by Paul Beal, Scarborough House, Lanham, Md., 1992)

And another reference, just for good measure:

YOU PAYS YOUR MONEY AND YOU TAKES YOUR CHOICE -- Punch, Vol. X, No. 16, 1846. From "Fundamentals of Risk and Insurance," eighth edition, by Emmett J. Vaughan and Therese M. Vaughan, John Wiley & Sons, Inc., New York, 1999.

I've always said "...and you takes your chances". A Google search shows mine's the rarer version, with 860 for "chances" and 3460 for "choices".
