Housemates have taken part in another Saturday Challenge, although this one was quite different from what has gone so far, not only because it lacked the "evil" edge that the others have had, but also involved people from outside of the house...

Each of the remaining six housemates were called in to the diary room, and had to identify the voice of the mystery celebrity that they were asking questions to, and can only get a "yes" or "no" answer in reply.

Dan was first up, and after using the full quota of 10 questions he correctly guessed Jim Bowen, meaning the housemates didn't lose £1,000 from the prize fund.

Shell also correctly Patrick Moore, and a very nervous and doubtful Nadia instantly got The Cheeky Girls.

However the dimwits in the house really messed up, with Jason failing to work out that the voice which was answering the yes/no questions was Paul Daniels - you'll like it, not a lot! Michelle failed to identify Chaz and Dave (possibly the hardest of the lot, although no excuse really), and "brainbox" Stuart failed to recognise Roland Rat, which is just a bloody disgrace!

He was none the wiser as to who Roland Rat was when he returned to the Sofa and saw him on the plasma screen either... HOW CAN THIS BE? ARE YOU A MORON STUART?

They lost a total of £3,000, which apparently went to charity as chosen by the celebs.
