Jimmy In The Box? Poem by Ima Ryma

In the backyard my dog dug up
A dirty bag that looked quite old.
But inside an ornate box, yup.
I wondered if I had struck gold.
Opening up the box I found
A note with some ashes below.
The words I read did sure astound.
But true or not, I could not know.
As I did ponder what to do,
My dog comes up real close and gawks.
And then my dog did sneeze and blew
Right on top of the open box.

Would remain a mystery no doubt,
If Jimmy Hoffa's ashes blew out.
