The big shock for Larry is not that his sister, Lora, is out for his blood.  What's most shocking to him is that he HAS a sister, period.  He has no recollection of her, even though they spent several years under the same roof.

While Larry had his share of problems growing up, Lora's childhood was no picnic either.  She informs Larry that after their father's demise, Lora's new perm so upset Larry that their mother sent her off to an inner-city convent.  There, she received martial-arts training, and went on to become a black-belt nun.

As Sister Lora tells it, she led her convent to five consecutive wins in the All-State Nun Competitions.
