McCain, Obama trade jokes, not jabs at NYC dinner

US Presidential candidates John McCain and Barack Obama swapped self-deprecating jokes instead of campaign jabs Thursday night, the Republican saying he had replaced his team of senior advisers with "Joe the Plumber" while the Democrat claimed his own "greatest strength would be my humility." Said Obama: "Contrary to the rumors you have heard, I was not born in a manger. I was actually born on Krypton and sent here by my father, Jor-el, to save the planet Earth," a reference to Superman. McCain joked that Democrats had already begun attacking Joe the Plumber, the Ohio man whom he repeatedly referred to in Wednesday night's debate, and claimed "that this honest, hardworking small businessman could not possibly have enough income to face a tax increase under the Obama plan." The two men spoke at the 63rd annual Alfred E. Smith Memorial Foundation Dinner, a charity event organized by the Catholic Archdiocese of New York for the benefit of needy children. An estimated $4 million was raised.
