From Bob Dole's humor compilation book, Great Political Wit:
In the depths of the Great Depression, Hoover and Coolidge found themselves together in Marion, Ohio, dedicating the memorial to Warren G. Harding. Hoover outlined all the steps he was taking to end the nation's economic spiral, making clear his resentment over what he regarded as unfair criticism from the public.
"You can't expect to see calves running in the field the day after you put the bull to the cows," said Coolidge.
"No," replied Hoover, "but I would expect to see contented cows."
Of course, to the extent that the Obama administration's policies are just as ineffective and counterproductive as Hoover's, there's little wonder the cows aren't contented.
