A Walk On Planks

Back into the lion's den to amuse
I hear sharks do smell fear

So for most in acts, parts  to soothe 
If I am to keep my head

Firmly fastened to my neck
I am to show no excite wobble

And not so, to be caught with fear
As a suit of white overalls worn

With the nuthouse this close by
Panic will hold sincere assured fall
