(Peggy is trying to explain to Bobby that men have attractions to different female body parts, while simultaneously convince him (and her) that her foot modeling will HELP women)
Peggy: ...some men like ladies' bottoms and other men like ladies' bosoms and a small, small number -- too few-- love ladies' big feet. Now, mommy is trying to increase that number and, thus, help women everywhere.
Bobby: How does this help the women with the big boobies?
Peggy: They don't need any more help.
