Ninja!

Where is he? Right in front of you - but you don't see him until it is too late.
He's a man of mystery - A shadow hiding within another shadow.
He's a Ninja!
The pyjama pants are part of the Ninja dress code - camouflage for when stalking his unlucky quarry.
Living in the somewhere between life and death, day and night, heaven and hell.
He's a Ninja!
He answers to no mortal.
Making moves that faster than even a trained eye can see.
Silently following the path of true enlightenment - never wavering.
He's a Ninja!

Half a dozen karate lessons and a Royal Easter Show bag have a lot to answer for.
