During the President's address to Congress on healthcare reform, Rep. Joe Wilson (N.C.-R) yells out that Obama is a liar.  Suggesting a secret plan to insure illegal immigrants, I guess?  What I find so amazing about this clip is how pissed Nancy Pelosi looks in the background, and how Joe Biden looks like a grumpy dad who is about to resort to the back of his hand.  Obviously, there will be many creative versions interpeting this exchange for us all to look forward to (I'm starting my mashup now).
