To try and get people to watch I bet they have chosen A Sex addicted, A Drug addict, An Alcoholic, A Transitive who after their operation decided to have another to turn her/him into a horse, A normal person(Or so we think until halfway through the show it will be revealed their a murder, who has been given the right to kill one of the housemates), A "Celebrity"(like a weather caster from a local station), A nudest, an ex Army man who will try and blend in with what ever area he is in, Santa Clause, Someone who thinks they're the next Jesus, Someone Who is opposed to the idea of locking people in a house for 12 weeks and will try and destroy the show from the inside(The will know of this already, but they think it will add drama) And A homosexual Chimpanzee. Then half way though(Just after one has been murdered) in a "Shocking and surprising twist" They will bring in a new house guest, Pickachu(Sp?) who will literally shock the other house guest every time they ignore him.
This is all guess work of course 😉
