What's your favourite conspiracy theory?

[Killearn Kitties]

I couldn't stop thinking about conspiracy theories yesterday, after the one about the moon landing being mentioned. There are, of course, dozens of conspiracy theories out there, but my favourite was always the Paul McCartney is dead theory. I've even heard an interview on the radio with a man who swears he was in the operating theatre the night Paul McCartney died 40 years ago.

Here is the "evidence". Death Clues

So what is your favourite?
