The first Have/Have-Not competition
The Houseguests in Season 11 were thrown for a loop when they learned about the first-ever Have/Have-Not competition, which was called "Big Brother Rave" and required the losing group would have to endure seven days of the most grueling living conditions in BB history. Luckily for Chima Simone, Michele Noonan, Ronnie Talbott, they partied through the pain and ended the week relatively unscathed.
Additionally, this season of Big Brother was the one that brought together Jeff and Jordan Schroeder and, as they say, the rest is history.
To see the inaugural Have/Have-Not competition and love blossom between Jeff and Jordan, watch Big Brother Season 11 on CBS All Access.
