For the first book, I interviewed one mother of four little kids, skinny, pretty, bad teeth - meaning no dental care - and the kids are jumping around, 'cause they want to hear their mamma's voice played back... and so I play it back, and she listens to what she said on the tape and she says, 'Oh my God,' she says. ' I never knew I felt that way before' ... That's pretty hot stuff, isn't it? That's hot stuff. That's the stuff.
