A running sketch they have on the show is when Fallon writes "thank you notes." I've never found it was amusing as most, but last night they had a wonderful twist on it. Instead of Fallon writing the notes, they had the female writers of the show's staff come to the desk and present their own "thank you notes." What made the sketch work -- and overcome a very high hurdle -- is that the notes had to reach the standard of being actually meaningful...yet also funny. And to their credit, they all were. That's no easy writing trick to pull off.
Clearly, Secretary Clinton knew about the segment ahead of time, since she wrote a "thank you note" herself at the end, but she wasn't informed ahead of time what was going to be said. And some of the notes were,in fact, very touching and it was obvious that she was particularly very moved by those.
What I like too is how she herself greets all the writers as they arrive, and initiates shaking their hands.
