On the March 15 edition of MSNBC's Countdown, host Keith Olbermann awarded nationally syndicated radio host Rush Limbaugh first place in his daily “Worst Person in the World” segment for Limbaugh's March 13 reference to married journalists Jay Carney and Claire Shipman as “slave master and ... husband.” As Media Matters for America documented, Limbaugh, during the March 13 broadcast of his radio show, initially referred to Carney and Shipman as “slave owner and husband,” before thinking better of it and changing “slave owner” to “slave master.”

From the March 15 edition of MSNBC's Countdown with Keith Olbermann:

OLBERMANN: But tonight's winner -- comedian Rush Limbaugh! Another friendly word from the master of courteous political debate. Referring to our former colleague Claire Shipman, now an ABC News correspondent, and her husband Jay Carney, the deputy Washington bureau chief of Time magazine, quote: “Claire Shipman and Jay Carney are, uh, slave owner and husband. Well, husband and wife, if you prefer that, and, and slave master. I take it back, slave master, not slave owner. Slave master and wife!” Unquote. Uh, yeah, pharmacy? I'd like to order some refills for Mr. Limbaugh. Rush Limbaugh, today's Worst Person in the World.
