It would be interesting if he did come back, but I think we're only really going to get any further if he either

1
presents actual evidence

or

2
admits that there isn't any more evidence to show.

In my oppinion this man is is going around the internet creating rubbish with only his website and a few scan photos that could just have blobs of gristle to support it.

Even so, it has been interesting nonetheless. Look how much debating people have done!
And everyone likes a good debate

I would still like him to return though.

His site is great for a laugh because lets face it he can't be serious.
I think he should start up his own comedy website and he could use pehaps some of these titles:

Are you really dead Prime Minister?
I did it!
A pain in the neck!
It wasn't the aliens - I killed the Prime Minister!
The Navy implanted me!
The CT Scams!
Harold Who!
I did it to them then they did it to me!
I took'em to court but no one believed me!
It's a cover up!
They call me Garry!
I choke every time I think of you!
I was in jail but I was innocent!
A Dingo took our Prime Minister!
My evidence cannot be silenced!
Swimming with the Prime Minister then drowning him!
I've got the affidavit!
How long can a politician hold his breath under water?
I invoke the second law of the universe!
They're an evil mob!
I've got a foreign object in my throat!
I can't change stations on my throat implant!
The CT-Scan proves it!
Everyone's evil but me!
They tried to silence me but I made up for it with lies!
The man who never knew too much!
It is what it is!
I invoke the otherside!
My antenna tickles my throat what tickles yours?
Someone's in my bodybag?
The frogger that committed fraud!
No one believes me!
The CT-Scan X-Files!
Its a cover up!
The politician that left me speechless!
I was underage!
Why don't they question me!
They experimented on me!
It's really, really, really really true!
You don't need evidence because I'm telling the truth!
Its been so long my throat is beginning to rust!
The lymph node diver!
My throat is alien to me!
I misplaced a Prime Minister!
I'm not a crook they are!
I was involved in clandestine acts!
I swear I did it!
Show me your implant and I'll show you mine!
The truth may surface but not this body!

These would all be great titles for this mans comedy carreer in the world of cover ups!
