My grandfather taught me an "ole rattler" verse in the late 1940's and it went like this:

Here Rattler here,
Here Rattler here.
Call Ole Rattler from the barn,
Here Rattler here.

A raccoon has a ringy tail,
A possum has no hair,
Shake him from a 'cimmon tree,
And touch him if you dare.

Here Rattler here,
Here Rattler here.
Call Ole Rattler from the barn
Here Rattler here.

Much to the chagrin of my wife and other relatives, Ive passed this along to my children and grandchildren and they sing it with delight. At family gatherings we'll get it started and everyone has a good time - outsiders have no idea what we're singing!
