Jay Leno: "The White House is now urging Americans not to 'read too much' into the other week's jobs report. In fact, they said it would be best if you didn't read it at all."

David Letterman: "The American League was defeated 8-0. The American League also lost the 2011 All-Star Game as well as the 2010 All-Star Game. Under President Obama, America's own league is on a losing streak! Mitt Romney will fix the American League and make it competitive again."

Bill Maher: "Mitt, pick me for your VP! I know it's out of the box, but look: we are complete opposites. Americans love that. It'll be like a buddy movie, where you're the uptight square and I'm Chris Tucker."
