3. Vice President Joe Biden — Biden survived the campaign, the transition and even Inauguration Day without any Obama-embarrassing verbal gaffes. But on the first full day of the Obama presidency, Biden made a joke — on live TV — about Chief Justice John Roberts’ fumbling of Obama’s swearing-in. Obama, who had tried to smooth over the oath of office glitch, looked visibly unhappy with his VP, touching his arm in a sign that it was time to shut up and move on. If Biden can’t button it — and encourage his wife to do the same — expect to see Obama’s pinched-face look a little more often.
