The Futurama Theorem

There was an episode of Futurama in which the writers had to solve a problem. They worked out by adding two extra people no matter how many people were having their brain swapped would mean that all the brains could return to the original person. That was a new development in mathematics it's called the Futurama theorem. I have a thing I'd like to bring up about this because I saw people talking about it because this Unicode news is new. This is a way that you can do like use Arabic numerals and you can basically make an eight in a certain way where it has eight angles but that's not a thing that happened intentionally.
