You're right, I could have sworn I heard it from a reliable source. Oh well. It appears it was done by this guy.

I don't feel sorry for Heston at all. Like you said, he knew what he was getting into, and Moore actually didn't ambush him very much until he avoided some very basic questions (ie: why did he feel the need to bring national NRA rallies to the sites of two horrible gun-related events only days after they occured). Only after he dodged those questions did Moore start attacking more.

The person I did think he ambushed (and for no really good reason) was Dick Clark. That was a tough correlation to draw, and I didn't think there was a connection there. It seemed more like a stunt to involve another celebrity than anything else.
