Diamondback Hat- Khaki

 These diamonds don't shine,
For they are not bright.
These diamonds tell lies,
Through forked tongue they will bite.

You look weary, cowboy,
Your home this is not.
Your steed is long gone,
and you just missed your last shot.

These diamonds don't shine,
Through forked tongue they take.
These diamonds tell lies,
Never trust a diamondback rattlesnake.
