Schooner Fare sang it a while back, like this:

O-ro the rattlin' bog, the bog down in the valley-o
O-ro the rattlin' bog, the bog down in the valley-o

And in that bog there was a tree, a rare tree, a rattlin' tree
With the tree in the bog
And the bog down in the valley-o.

Now on that tree there was a limb, a rare limb, a rattlin' limb
With the limb on the tree and the tree in the bog
And the bog down in the valley-o.

Now on that limb there was a branch, a rare branch, a rattlin' branch
With the branch on the limb and the limb on the tree and the tree in the bog
And the bog down in the valley-o.

(Repeat, adding a line each time)
Now on that branch there was a twig, a rare twig, a rattlin' twig.....

Now on that twig there was a nest, a rare nest, a rattlin' nest.....

Now in that nest there was an egg , a rare egg, a rattlin' egg.....

Now in that egg there was a bird, a rare bird, a rattlin' bird.....

Now on that bird there was a feather, a rare feather, a rattlin' feather .....

Now on that feather there was a flea, a rare flea, a rattlin' flea .....

(Last line courtesy of the late great Tom Rowe)
And on the flea, there was a rash...
