@glitterbag,
I remember that clip-Hannity was chuckling because Hillary was visibly annoyed about the African student's question to her which asked for "Mr. Clinton's opinion through the mouth of Mrs. Clinton". The questioner clearly comes from a background where women are not allowed to exercise authority over men, hence the African student's phrase which made it seem as if Mrs. Clinton had to legitimize her authority by supposedly being the representative of her husband.
Obviously, to play along with the African student's phrase would be out of the question, for to do so would betray Mrs. Clinton's position of being an exponent of equal rights for women. Which is why Hannity, whose audience is largely of the "barefoot, pregnant and in the kitchen" variety, loved the question.
I forget if that incident happened before or after Hannity got bumped from his prime 9 PM time slot to make room for Megyn Kelly's show.
