Just thought I'd throw this wording in as its the one I remember from childhood:

(Chorus)
1,2,3,4,5,6,7,8,9,10.
10,9,8,7,6,5,4,3,2,1.
1,2,3,4,5,6,7,8,9,10.
10,9,8,7,6,5,4,3,2,1.

Mary the milkmaid was milking a cow,
The trouble with Mary, she didn't know how,
Out came the farmer and gave her the sack,
So she tipped the cow over and poured the milk back.

(chorus)

To market, to market with my brother Jim,
When someone threw a tomato at him,
Tomatoes are soft but this one killed him,
For this tomato was wrapped in a tin.

(chorus)

I called on my girlfriend, her name is Miss Brown,
She was having a shower and couldn't come down,
I said, "Slip on something, you'd better be quick."
So she slipped on the soap, and by god she was slick.
