Stephen Colbert Interviews 'The History Of White People' Author Nell Irvin Painter: All You Have To Do To Change Race Is Have Sex (VIDEO)

"The History of White People" author Nell Irvin Painter was on "The Colbert Report" last night, and gave few answers about the nature of race, though she did raise a number of interesting questions. Painter, a black woman, suggested that she herself could be considered white because of her education level alone. She posits that race is entirely fluid, and said that the best way to change your race is to have sex.

Colbert and Painter had a hilarious rapport, at one point resulting in an arm wrestling match over Stephen's Irish heritage. Stephen had a hard time wrapping his mind around Painter's ideas: "White is the default race," he said.
