Furious Fowl

If your birds are upset,
And some swine are snooping round,
It makes total sense,
That a catapult be found,
Into which you place,
The angry avians you see,
And watch each porcine face,
When hit by flung poultry.

Now you may be in wonder,
Why it is the birds don't fly,
"Why a catapult?" you ponder,
Instead of wings to get them by,
But it really doesn't matter,
I really wouldn't ask,
They're each mad as a hatter,
They might take you to task.

So with careful aim,
Teach the pigs what for.
These birds aren't tame,
They are angry, out for war.
No wooden tower,
Or icy outcrop will be safe,
When wrathful feathery power,
Lays the porky land to waste.
