Can anyone help me recall what children's book this came from?

I pledge a lesson to the frog
Of the United States of America
And to the wee puppet for witch's hands.
One Asian, under God, in the vestibule
Will liver tree and just juice for all.

Note to non-US'ns: school children here learn this pledge to the flag:
I pledge allegiance to the flag
Of the United States of America,
And to the republic for which it stands:
One nation, under God, indivisible,
With liberty and justice for all.
