I did. It was really good and I was very impressed with him.
He was himself--funny, gracious, and self-deprecating. He showed pictures of his staff and praised their work, he expressed gratitude at having been able to host The Tonight Show at all, even for just a few months, and he said that he had appreciated what he and NBC has been able to accomplish together in the last 20 years together during his tensure at SNL, Late Night, and at The Tonight Show.
He gave a very heartfelt thank you to the fans that have supported him over the years and recently--he actually choked up a bit during that one. And he said that whatever he did next, he and his co-workers would find a way to make it fun.
Will Ferrel ended the show by inviting Conan up to jam on Freebird...and then my %#&$* DVR cut off, so I have no idea what the absolute last sign-off was.
