“I swear on a stack of bibles, I didn’t do anything. I swear I didn’t. If I did, I’d say so,” he insists on Wednesday’s Dr. Phil.

“Well, how do I know what your private parts look like if you never touched me?” Jessica asks. She claims Bob started molesting her when she was 6 and would make her shower with him.

“I didn’t have you get in the shower, you jumped in the shower. That was your idea, not mine,” he says.

“Can I point out that my sister is seven years older and what he did to her happened first,” says Kim. “So why would she say that he’s doing things if he didn’t, and then have it magically happen to me too?”

How does Kim respond when Jessica says she blames herself for not saving Kim from Bob’s abuse?
