What A Duck Can Not Do

Who can say what a duck can not do,
To see it jump from a lilypad like a frog.
And jumping to another done fast.

Who can say what a duck can not do,
One day to see that duck as a rat.
Then glide away like a pompous swan.

Then glide away like a pompous swan,
That rat.
Some days AND nights.
From dusk until dawn.
That rat.
Looking like a duck.
That rat.
Clever but will never be a swan.
That rat.
To be gone.
From dusk until dawn,
Much too long.
That rat.
And a duck can't undo,
Being eaten up by fat cats!
