Anyone that knocked up the one claiming to be pregnant has got serious mental issues.
I've seen a longer version of this. After a few hours in holding cell, the chubby older one was identified. She has a long rap sheet, is a drug abuser, and not pregnant. She wound up spent and self pitying. A couple of hours in the holding cell calmed both of them a lot.
They always claim that. One of many on the bingo card.
