This documentary segment aired back in 2006 when Abigail and Brittany were turning 16 and just getting their driver’s license. Abby and Brittany are unique in their circumstances because they are one of only a few number of cases of conjoined twins that have apparently lived long enough to enter into adulthood. The two of them share one body but each control one side with the ability to do completely separate things without creating much disturbance to the other. In addition, the two have a remarkable ability to work together on a number of things including clapping, typing, and driving a car.

Believe it or not, Wikipedia has a list of their organ distributions. [via]
