They booed him during a joint session of Congress in 2005.

The outburst would not be appropriate if it was planned.I do not think this was the case I think he just got fed up with the lies just as most of us have and his outburst conveys that frustration.

I agree with your assessment. He had to sit there and listen to Obama pretty much call all of the Republicans liars.
