The title of the video mentions him being surprised, and...well, he his. Often talk shows have a guest being surprised, and they are, and it's sort of cute and then it's over, fine. But this...well, they do surprise him. But the thing that makes this video so terrific is who the person being surprised is, Mandy Patinkin. He's just so warm and friendly and thrilled that it is an utter joy and he allows you to share in his being enthralled.
Also, it's worth nothing ahead of time that after a few minutes, as you enjoy the piece, you look at the clock and wonder, hmm, how can they can this conversation going for 10 minutes?? It's lovely and charming, but can it sustain that long.
Well...as you've noticed, I haven't said much about what actually is going on. And I won't. All I will say is stick with it, it does sustain for 10 minutes.
And Mandy Patinkin comes across great.
