From the New York Times this morning, a fun little history of recent live-mic "gaffes," starting with yesterday's:

Senator Lindsey Graham has witnessed enough congressional hearings to know: If you want to have a side conversation, cover that microphone.

Mr. Graham, a top Senate Republican, seemed to forget that lesson on Thursday when he was caught on an open mike offering to help Secretary of State John Kerry cajole Speaker John A. Boehner into supporting an expansion of loans to Ukraine through the International Monetary Fund.

“Hey, John, good job,” he told Mr. Kerry, referring to the secretary’s just-finished testimony on the State Department budget. “Let me know what I can do to help you with Boehner.”

That's a good one! But I'm still partial to our own Seattle City Council member Bruce Harrell's aside after some testimony earlier this year, when he called local public-testimony showboaters Sam Bellomio and Alex Zimmerman "a bunch of assholes."
