Curb Your Enthusiasm, The Reunion

This is such an incredible scene for several reasons.  For one, the high concept of it - both in it being a reunion show within a different show to begin with, and for Larry David playing the character that was, for all those years, based on himself.

But what puts it over the top is what a well-known, beloved character George Costanza is.  As in, if any one of us was asked to do the scene as George, we'd say the exact same things, with the same gesticulations and tone; everything about it, really.  Perfect.
