Iggy pop? Frankly it doesn't wash with me; don't you know all conspiracy theories are put there by the government to scare us?
Maddest conspiracy theories I've heard in order are:

1) the FBI organised the twin-towers act so they could invade some oil countries. (I hope nobody will regard my mentioning of this tragic and sensitive event as tasteless).
2) the American's never went to the moon, it was all shot in a studio and broadcast to piss of the Russians.
