'Shark Tank's' Lori Greiner: 'I can tell instantly if something is a hero or a zero'

lori-greiner-shark-tank-325-abc.jpg Zap2it: How did you come to be one of the investors on "Shark Tank?"

Lori Greiner: Several years ago, I met with [executive producer] Mark Burnett, and he thought I would be right for the show. That's how it all started.

Zap2it: The session that just finished taping was painful to watch - the person seemed unprepared for the questions and concerns. How do you feel about it?

Lori Greiner: It was an interesting, clever concept and a way to get into the "Tank." He convinced the producers to get in here, so I commend him for his ingenuity. But once he came in, he wasn't a closer.

Zap2it: Do you enjoy making deals in this format?

Lori Greiner: I can tell instantly if something is a hero or a zero, and I do believe that's true. I have a lot of experience and practice. So for me, I love the format. It's invigorating and exciting. I still learn every day from the other sharks. But I love it. I'm in my element.

Zap2it: Fellow shark Kevin O'Leary has a prickly on-screen relationship with the other female shark, Barbara Corcoran. How about you?

Lori Greiner: Kevin and I have an interesting relationship. I wouldn't call it abusive; I've learned a way to tame the shark. Let's put it this way:?He doesn't bite.

Zap2it: How do you get along with shark Mark Cuban?

Lori Greiner: All the time, I'm challenging Mark. But I also listen to what he has to say, because it's bad when you stop learning.
