Several somebodies actually, and I think they were much chagrined by it.
You can watch Obama's entire health care speech here, as well as the official Republican rebuttal immediately following.
I thought it was an awesome speech and I think the Republicans who are against it are just smoking crack (and by "smoking crack" I mean pandering to special interest groups lobbying for the status quo who are probably lining the Republicans' coffers in ways that should be and might actually be illegal).
As to what was going on in the House while Obama was talking: What the heck were those sheets of paper that some of the Republicans kept holding up? And that tasteless asshole, who shouted out that Obama is a "liar" right in the middle of his speech, Rep. Joe Wilson from South Carolina (whose web server crashed minutes after he did that, btw), needs to go home now.
