If you really think about it. They reunited two half siblings who had no idea of each other's existence on national television (Nakomis and Cowboy, Big Brother 5). They put a daughter and father who were not speaking to each other and on horrible terms in a house together (Dani and Dick, Big Brother 8). And they put a bunch of exes together for Big Brother 4, which led to a violent outburst from Scottie who was expelled and was actually going through some shit and seeing his ex flirt with other guys.
