That woman obviously came from a neglectful family herself. Her husband was going off to Iraq, which is what led to Jo being called in. Apparently there was concern over whether the woman could "handle" the children while he was gone. The guy looked kind of older so perhaps in between stints in the military is when they managed to procreate all those children. Or perhaps it was a mixed family, I couldn't really tell. The fact that all the children were female means chances are good they will grow up to be mothers very similar to what we saw on TV... and so on and so on. Supernanny producers should start a scholarship fund to be used for counseling when they get ready to have children of their own. Or they could opt for free sterilization... not that I believe in a supreme race or anything.
I agree with DD. Afterall, the Humane Society requires applications and education for adopting a cat.
