Keith Olbermann explained what went wrong at Current TV by telling David Letterman he was a "$10 million chandelier" without a home to hang in. Rush Limbaugh agrees that the fired host should describe himself in terms of a household lighting fixture ... just not one quite so precious. "You're the guy wearing a $50 lampshade sitting in the corner of the room that nobody else wants to go in," Limbaugh said yesterday. "That’s what you are. Not a $10 million chandelier. Gee."
