Corn is an essential part of the American diet, and part of how Stephen Colbert and his highly skilled graphics team took down Tom Vilsack.

On the other hand, corn is also a key ingredient in ethanol.

On yet a third body part, judging from the number of posts it has generated on the Colboards, corn seems to have become the source of an unnatural, and perhaps unholy fixation for certain members of the Colbert Nation.
