Very similar to some above:

Well I went into town and I walked arond the block
And I drifted into a do-nut shop
And I picked a do-nut out of the grease
And I handed the lady a five cent piece
She said, "This nickel's no good to me
There's a hole in the middle of it you see."
I said, "Pretty Missus now don't be blue
There's a hole in the middle of the do-nut too."

The chorus I've always sung:

Turkey in the hay, in the hay, in the hay.
Turkey in the straw, in the straw, in the straw,
Pick up your fiddle and rosin your bow,
And play a little tune called Turkey in the Straw.

or

Turkey in the hay, in the hay, in the hay.
Turkey in the straw, in the straw, in the straw,
I danced all night with me mother-in-law,
While the band played a tune called Turkey in the Straw.
