House Republican leader John Boehner of Ohio with tears in his eyes as he celebrated the GOP's victory in 2010 that changed the balance of power in Congress. It seems a strange sight: The president of the United States, sometimes called the most powerful person in the world, breaking down in tears thanking campaign workers for their work on his behalf. But Barack Obama isn't the only world leader unashamed or unable to avoid being seen crying in public. As Speaker of the House, Boehner holds one of the most powerful positions in the U.S. government, and he cries so frequently that Twitter jokesters have taken to calling him the weeper of the house.
