Johnny Dollar's Place has the video of an amusing exchange on this afternoon's Studio B:

SHEP: What do you do next today Greta?

GRETA: I'm not going to tip off CNN, they already followed me to the last interview--

SHEP: They should have never let you go! I bet they're wishing they never let you come over here! Anyway, go ahead--

GRETA: I had many wonderful years at CNN. When I've got a great interview, they show up a half hour later. I'm going to keep that a secret between us Shep, but I've got something I want to do this afternoon.
