Well, I haven't actually decided yet. I know it's not Invasion of the Body Snatchers as that's just plain stupid - for a start, they didn't snatch the bodies, they just kind of used them as hosts. Invasion of the Personality Invaders would be a little bit more accurate but hardly likely to cause world-wide panic.
Invasion of The Giant Badgers from Saturn would be more frightening but slightly obvious and as badgers don't have opposable thumbs, they would be unable to use guns or grenades so it would be a very short invasion. It fact, it would be little more than a day trip really. Although, I don't actually think badgers take day trips as they don't have picnic hampers.
Therefore, I believe it's just plain aliens that are taking over planet Earth. I have come to this conclusion because I have noticed sporadic outbreaks of previously sane and logical people coming to absolutely ludicrous conclusions. Some of these outbreaks have occurred in a surreptitious manner and there can therefore only be one explanation -
THE ALIENS ARE HERE
I'm not the first to have postulated on this hypothesis - numerous authors have written books, films have been made, a typical example being Men in Black. In this film, the theory was that extra terrestrials had already been assimilated into the human population (which I concur with).
Michael Jackson - I'm black, I'm white, oh shit I've forgotten which colour I'm supposed to be.
George Bush - Enough said really.
Margaret Thatcher - 'What'd do you mean you gave me a womans body?' *laser blast*
Gary Oldman - (The shape shifter) "He was NOT in that film" *titles roll* "Aw fuck, he was".
Jesus Christ - 'My dad is God and you can't kill me - I will live forever Bwahahahahahah'.
Tiger Woods - *Transmit to Tiger* Start playing crap, you're standing out too much *end transmit*
Joan Rivers - 'This skin doesn't fit, staple it at the back again will you?'.
I'm sure there are quite a few others I forgot.....????
