the MTV "reality shows have been exposed as faked, Operation Repo is another notorious one. others have a mixture of "real" and "staged" segments (im thinking of this season's premiere of Billy the Exterminator, some scenes in Dog the Bounty Hunter). also, where do you draw the line? some "reality" shows depict real people having real conversations, but they are shot multiple times to gain extra footage for style (Jerselicious; friend of mine was witness to a scene in hoboken, they did at least 3 takes, though the conversation itself may have been "real")
