Mutiny over BB ball games ban
The stresses and strains of continued incarceration inside the Big Brother house were starting to show as contestants launched an insurrection over a rubber ball.
Housemates Sam and Dave mounted the mutiny following Big Brother's edict banning ball games for fear of damaging lights and fittings on the set of the Channel 4 programme.
London-based graffiti artist Sam and Welsh Christian minister Dave led the rebellion after being told off by Big Brother for playing with a ball.
Complaining that the contestants were being banned from having any fun Sam, 21, broke the rules of the house covered up a number of cameras with clothing.
Sam and Dave turned lawbreakers again by hiding under the "nest" area where the Big Brother cameras cannot reach.
The pair now face the threat of punishments for their disobedience.
The bad behaviour comes after it was revealed that four housemates will be evicted on Friday as the 11th series enters its closing stages.
With just nine days to go until the final, the fate of the nine remaining housemates has been left in the hands of viewers.
The vote to evict phone lines opened after Jo became the eighth housemate to be booted off the show on Friday night.
Josie was earlier chosen by housemates to receive a free ticket to the final, which will be held sooner than originally planned, on August 24.
