WASHINGTON, DCRepresentatives from the National Corn Growers Association put the screws to several U.S. senators in a meeting held at an undisclosed Washington hotel Monday. 'If you guys don't support an increase in the National Plant Genome Initiative budget, we'll shuck you like an ear of freshly roasted Iowa sweet,' NCGA CEO Rick Tolm said, idly twirling a double-pronged, cob-shaped corn holder in his hand. Senators reportedly promised they'd vote for the budget increase after Tolm threatened to throw them in hot oil and watch them pop.
