James Earl "Jimmy" Carter, Jr. (born 1924) served as the 39th President of the United States from 1977 to 1981 and was the recipient of the 2002 Nobel Peace Prize, the only U.S. President to have received the Prize after leaving office. Before he became President, Carter served two terms as a Georgia State Senator one as Governor of Georgia, from 1971 to 1975, and was a peanut farmer and naval officer.

Jimmy Carter appears in "Black Mystery Month" as the second "President Peanut", head of the "Illuminutty" and protector of the "Jar of Proof", a scroll containing the various names Abraham Lincoln tried to come up with for peanut butter before his assassination delayed a plot to give credit for the invention of peanut butter to a black man. When he convinces Stan to give him the jar he tries to destroy it by dropping it into lava flowing beneath Washington D.C. and falls in himself.
