I found this in a book of "Mad Art"; art from old issues of Mad Magazine. It was just too good not to share:
Tweedledum and Tweedledee
Were called to Washington
To solve the economic mess
And see what could be done.
They talked of things like price controls
Of more aid to the states
Of tax deductions, welfare boosts
And higher tariff rates.
The more they talked, the more they fought
As only experts
