h/t The HuffPo:

David Letterman had CBS News anchor Katie Couric doubled over with laughter when he referred to Rush Limbaugh as a "bonehead" and described his shirt-unbuttoned appearance at the recent CPAC conference as that of an "East European gangster."

Well at least Letterman's not cow-towing to Limbaugh but Katie's sounds disappointed she might not get her interview with him. Cry me a river. Rush might get a little less free air time to bloviate.
