Sen. John McCain (R-Ariz.) went on the Colbert Report to discuss his new book, "Thirteen Soldiers." He and Stephen Colbert discussed the situation in the Middle East, Secretary of Defense Chuck Hagel's ouster and deep frying turkeys. He refused to say if the War on Christmas was covered in his book, but got big applause when he said his book proves that women can serve in combat and joked that he was thinking about running for president in 2016.

He also forgot that Colbert teaches Sunday School, and got schooled on Bible verse.
