Non-swimmer Simon thought that the underwater challenge would be a good one for him to risk the food supply to his starving camp mates. As gamblers go, he is either a high roller or a bit stupid. As Doctor Bob applied the oxygen mask to a rather grey-looking singer, I think we made our mind up on that one.

Perhaps it was the spirit of Christmas that prevailed in the camp today, as a new sentiment of harmony and good will to all men spread through the jungle. Maybe Nicola and David got an extra large chocolate in their advent calendars. Who knows? Nicola said she had "buried the hatchet" with David – which is odd since she has spent the last two weeks wanting to plant one in his head.

Dressed in an itsy bitsy teeny weenie polka dot bikini, Nicola went about gleaning the treasure task with true page three gusto. From a programme maker's perspective, that girl delivers at every level.

Something important must have been entertaining the gay vote last night, because both George and Brian were up for the chop. Rather like a climber with a really tentative fingertip hold on a cliff, Brian has hung in there for an unfeasible amount of time. Maybe it is something about a politician’s make-up – thick skinned and impervious to unpopularity, no matter how much it is shoved in their face.
