A Tough Week for the Candidates -- and the Knicks

David Letterman: "Rick Santorum now says he's against separation of church and state. But he's not against separation of sweaters and sleeves."

Jimmy Fallon: "It was a tough game for the New York Knicks last week. Jeremy Lin went just 1-for-11 in their loss to Miami. Only 1 success out of 11 attempts — or as Newt Gingrich calls that, ‘primary season.’"

David Letterman: "All these GOP debates. They had debates with podiums, debates with chairs, a table, bunk beds. Now the next one is going to be in black-and-white and silent."

Craig Ferguson: "President Obama is trying to come up with a new campaign slogan that would replace ‘hope and change.’ He's thinking of going with ‘I am not Mitt Romney.’"
