I'm re-familiarizing myself with my office and surroundings (and e-mails and invitations and outstanding issues) after an absence of about five weeks -- and as we all know by now, more than 40-thousand miles of travel. To those of you who watched our "Stand Up 2 Cancer" special from L.A. Friday night: thank you. It was a wonderful, emotional evening. I've never had reason to be so thoroughly impressed with so many celebrities before -- nor do I hang with those types often -- but what an incredible bunch. On behalf of everyone who had anything to do with it, thanks. We're back at it, covering politics and weather and finance and more. We hope you can join us tonight from...New York!
