London (CNN) -- French President Nicolas Sarkozy and his U.S. counterpart Barack Obama have come under fire after they were overheard talking rudely about Israeli Prime Minister Benjamin Netanyahu at the G-20 summit. Sarkozy was overheard telling Obama: "I can't stand him. He's a liar," according to French website Arret Sur Images. Obama is reported to have replied: "You're tired of him; what about me? I have to deal with him every day." The comments have provoked criticism in Israel and the United States -- but it is not the first time a prominent figure has been caught off-guard, on-mic. CNN looks back at 10 of the most infamous gaffes.
