President Obama is taking heat after his candid comments to Russian President Dmitry Medvedev were picked up by reporters’ mics. He’s hardly the first public figure to unknowingly have private comments become very public. We’ve gathered the best caught-off-guard moments.

In 2000, then-presidential candidate George W. Bush made a “major-league” gaffe when he was overheard bashing New York Times reporter Adam Clymer on the campaign trail. You’ve got to see what running mate Dick Cheney said in response.

In 2009, President Obama was overheard talking about Kanye West rushing on stage during Taylor Swift’s acceptance speech at the MTV Video Music Awards. Obama’s pop culture comments got him in trouble.

Remember Rev. Jesse Jackson’s headline-making open mic moment in 2008? Using some colorful language, he was seen talking to a fellow guest on Fox News about how presidential candidate Barack Obama was “talking down to black people.”

President Ronald Reagan did it, too, but he wasn’t talking to just one person. During a sound check before a radio address in 1984, President Ronald Reagan joked about bombing Russia. Check out all these moments and even more favorites in the video below.
