Bill O'Reilly clashed with David Letterman during his appearance on The Late Show Friday night. Letterman took O'Reilly to task for his over-simplified views and "bonehead" remarks.
O'Reilly tried to reduce the Iraq war at one point, saying "Do you want the United States to win in Iraq? It's an easy question," to which Letterman replied, "It's not easy for me because I'm thoughtful."
As the Huffington Post reported earlier, Letterman also told O'Reilly, "You're putting words in my mouth, just the way you put artificial facts in your head."
