By, me.

There is a duck outside my window.
He stands at attention,
and quacks in loud alarm.

I do not know for what he quacks;
perhaps it is to charm.

All I do know that if he continues
his noise producing ways,
I will be powerless against the urge
to cause him horrible pain. 

So to you dear offensive window dwelling duck,
I offer this plea;
Cease your obnoxious clatter, 
Or I will be forced to fuck your shit up.
