Joe Wilson's cat call ("You lie!"), for which he apologized, was the most egregious display of childishness last night by the House GOP.

But it wasn't the only sad display:

But while the majority of both parties' lawmakers behaved as adults, the insolence by House Republicans stole the show. There was derisive laughter on that side of the chamber when Obama noted that "there remain some significant details to be ironed out." They applauded as he spoke of "all the misinformation that's been spread over the past few months." They laughed again when he said that "many Americans have grown nervous about reform."

When Obama addressed the charge that he plans "panels of bureaucrats with the power to kill off senior citizens," someone on the GOP side shouted out "shame!" The president went on: "Such a charge would be laughable if it weren't so cynical." "Read the bill!" someone shouted back. Obama mentioned those who accuse him of a government takeover of health care. "It's true," someone shouted back.

Even as Obama delivered a tribute to the late senator Ted Kennedy, Rep. Tom Price (R-Ga), a leader of House conservatives, perused his BlackBerry. Shortly before the speech ended, Rep. Patrick McHenry (R-N.C.) walked out to beat the rush.

This morning, the conservosphere is lining up to demonstrate that Democrats booed and hissed Bush when he gave a State of the Union in 2005.  Except what they were booing and hissing at wasn't Bush, but at what Bush was saying.  Bush was warning that if something wasn't done, Social Security would fail.  That prompted a boo — the spector of Social Security failing.  It was not an attack on Bush, but an acknowledgement in agreement with Bush that losing Social Security would be bad.

But I suppose that;s a little to nuanced for conservatives to understand.
