Conjoined twins obviously come as a package deal, so you'd expect them to enjoy a few perks in life - but Abby and Brittany Hensel seem to have been had over.
The famous pair, aged 34, share a bloodstream and organs from the waist down as well as their earnings, so it's a good job these sisters get along quite well.
I suppose they're sort of sharing a husband these days too, seen as though it recently emerged that Abby had got hitched to nurse and US Army veteran Josh Bowling back in 2021.

Despite having just one body, the dicephalus conjoined twins insist that they have two souls, just like they have two hearts, two brains, two sets of lungs and two stomachs.
Each of them are their own individual person - but Abby has control of the right limbs, while Brittany is in charge of the left hand side, so they share the workload of everyday life evenly.
As fifth grade teachers in their home state of Minnesota, they also divide their responsibilities at work too.
But although the school are getting double the brain power, they are only paying for the price of one and the conjoined twins are given one single wage which they share between them.
Although they have two teaching licences and have got four eyes on the classroom instead of two, this isn't reflected in their finances.

Abby, who shot to fame with her sister on their TLC reality TV show, told the BBC: "Obviously right away we understand that we are going to get one salary because we're doing the job of one person.
"As maybe experience comes in we'd like to negotiate a little bit, considering we have two degrees and because we are able to give two different perspectives or teach in two different ways."
Brittany added: "One can be teaching and one can be monitoring and answering questions.
"So in that sense we can do more than one person."

OK, that's one thing.
But the kicker is, the pair were considered as individuals within the school system and have two separate degrees.
The sisters - whose parents always encouraged them to develop their own minds - both graduated from Bethel University with majors in education in 2012.

They had considered pursuing different subjects for their concentrations as part of their major, although they then realised the amount of extra coursework they would have to get through would be too much of a strain.
At high school, they only had to pay one set of tuition fees, but two sets of registration fees, NY Daily News reports.
Teachers put 'a sheet or a book inbetween them' so they couldn't copy each other in exams.
Abby and Brittany run into a similar situation when organising their travel arrangements - as they have two passports, but one ticket when travelling as they only need one spot on the plane.

Similarly, they both had to sit written and practical driving exams separately, as although they have to be coordinated, state law in Minnesota requires them both to each have a license.
