I like watch as well--it's fun to see people turn into paranoid, crazy nuts!
The USA Big Brother 4 starts July 8th at 8pm EST! I have a RealOne account for CNN and other News sites, and it covers the online BB Show as well.. What happens on the NET is so funny... You hear the BB Guy coaching them for their weekly challenges and stuff..
It's kinda like set up, and most of these people are in Hollywood or the 'business' anyway!! So it's not 100% reality. I dunno about the other non USA shows.. are they also kinda set up?
