mr. valentino is here! >> rudolph, at last you have come to beg my forgiveness, well, it is too late for that! >> carol burnette of her most famous characters, nora desmond, and the chemistry between carol and tim conway. i have never seen the crew so excited. they have been bouncing off the walls, carol, welcome back. >> thank you. >> you said his improv was pure gold and wildly inventive. was that part of the magic? >> totally, totally, on fridays we would tape the live show with the audience, and we would make chan changes, then another audience would come in and we would do the second show, well, tim -- i'm going to talk as if he is not here. he would do the first show as we had rehearsed it, to the ink. and then he would go to our director and say did you get all the shots, dave and so forth. okay, for example he would say, all right in the hotel sketch when we do this again on the second show, instead of being on a waist shot of me, be on a head to toe. that is all he would tell him. and the crew didn't know. and so it was like he was going to wing it. and he thought of something to do with that window.
