As an expert on 'Who Wants to Be a Millionaire,' Margaret Cho leaves a lot to be desired. A contestant uses her "Ask the Expert" lifeline on a question about tennis, but Cho knows nothing about sports and is mystified.

"I don't even know what sport this is. Is it football? Please give me a question about Nicole Richie!" Cho said.

Eventually, Cho offers this: "All I can say is, Tiger Woods? Does this have something to do with Tiger Woods? Because that's the only other person I know ... because he's Asian."
