Quack! Quack!

'''Quack! Quack!''' is an installment in the Reginald Livingston Seagull series. The poem originates from the Dr. Seuss book, Oh Say Can You Say?

Poem
We have two ducks. One blue. One black.

And when our blue duck goes "Quack-quack",

Our black duck quickly quack-quacks back.

The quack Blue quacks make her quite a quacker,

But Black is a quicker quacker-backer.
