Vice President Biden's few seconds of shut eye during President Obama's speech have the Beltway buzzing. But luckily for Biden, he's not alone. Several other prominent Washingtonians have taken naps during key events before. President Bill Clinton fell into a deep sleep during an event honoring the late Martin Luther King, Jr. in 2008. Senator John McCain caught some shut eye during President Bush's 2007 State of the Union address. And Dick Cheney took a snooze during a cabinet meeting in 2007. Check out the video posted, see above!
