Obama should challenge the Republicans to do this once  a month because Obama did a great job of dismissing many GOP attacks right to their face. My personal favorite was when Republicans stated that they had a stimulus plan that would cost half as much and save twice as many jobs and then Obama went back at them saying (I am paraphrasing) "if that was the case, why wouldn't I do it? I am not an ideologue, but I could not find a credible economist who said your plan would work" He then went on to point out that the stimulus was 1/3 tax cuts and the rest went to things like extending unemployment benefits and paying for infrastructure projects and challenged them to state what exactly they did not like about that.
