NBA Commissioner David Stern asked reporter if “he had stopped beating his wife”,,,sarcastic retort or out of bounds?

David Stern would have to be classified as a man of a certain age. Yesterday he was on the radio with Jim Rome. Rome can be a jerk and he asked Stern if the NBA draft was rigged? A ridiculous question and Stern responded with a ridiculous reply. Stern asked Rome if he had stopped beating his wife.Was Stern’s response insensitive or appropriate? http://content.usatoday.com/communities/gameon/post/2012/06/david-stern-asks-jim-rome-if-hes-stopped-beating-his-wife/1?csp=Dailybriefing
