What a marvelous day!

Talk about living with differences; I met Abby and Britaney Hansel, two people in a joined body with independant minds and shared body parts. How do you describe the phenomenon of conjoine twins?
They are a lovely 'entity'; and just when I thought that being bi-bionic with three ligaments in my neck fused with metal (I cannot go through a metal detector unanounced), was a unique and indespensable way of living on the third rock from the sun, I make the aquaintance , cybernetically , of course, of two lovely girls conjoined and independant of thought.

In my exoteric search for meaning, I come across two conjoined peaople and find out today's word. How Bizarre???
