I am

I am that busy man to ask,
I am the rule to your exception...
Me? - I'm the jack without a trade.

I am where the passing time goes,
I am where the lost youth is found...
Me? - I'm the 0.1% of germs that domestos won't kill.

I am the good thing which never ended,
I call a spade an implement to dig with...
Me? - Call me the medium cheese!

I am the round hole your square peg wont fit into,
I never look a clothes-horse in the mouth...
Me? - I'm the song the fat lady sung

 I am!
