One idea for a Katie sign-off. She is sitting facing the lights in the white blazer she wore the first night. I think (someone help me here) she might have been asking for help with the sign-off. The camera goes behind her and you she that she throws open her blazer and bares herself. It was very dramatic. And very funny.
She can even say the same thing Jane Curtain did on SNL after she ripped open her blouse and exposed her bra;
"Try these on for size, Connie Chung! If it's raw news you want, it's raw news you get!"
She could pull (off) a Sharon Stone "slouching in the chair under the lights" act ...
