And we have a surprise at the top of our "instant index" tonight. A new head-turning college freshman. Well, look here. You see him there in the middle. That, of course, is watson, the super computer who trounced humans on "jeopardy." He has enrolled at rensselaer institute in upstate new york to be modernized in english and math. And programmed to understand images and videos on the web. By the way, we're told, for now, watson will be living offcampus. And, look who is back. Remember this moment? Hello gorgeous. Reporter: That was barbra streisand, winning the oscar for "funny girl" in 1969. And today, an announcement. For the first time in 36 years, streisand will perform again at the oscars. And as you know, she'll be the second big voice on the stage this year. Recognize the other one? ♪ It's the skyfall ♪ adele and streisand on one stage. 25 days until the oscars. Stay tuned.
