This week's task requires the housemates to talk at length on Big Brother's chosen topics, and subsequently, be tested on one another's ideas.

On Sunday, they were each called to the Diary Room to offer their viewpoints on life after death, the existence of aliens and dating rituals.

And here's what they had to say...

On 'life after death'

Scottish saint Cameron had, predictably, some interesting ideas to present to Big Brother on this small matter.

"I think people either go to heaven or hell," he announced decidedly. On death - in Cam's expert opinion - the soul is presented to God, and the almighty one will say either 'you have been pure,' in which case the entrant will proceed to heaven, or 'you have not been a friend - go away,' in which case it's the pits of hell for them.

Jon had other ideas. "I know for a fact God doesn't exist," proclaimed the scientist from Staines. Big Brother was keen to hear what evidence Jon could present to support his controversial claim. "Well you don't see many miracles happening nowadays," came his response.

On 'life on another planet'

Scott seems fairly convinced that alien beings exist, but is doubtful they've reached earth yet. "I don't think they're among us...I don't think that any of my housemates are aliens. It's possible, but not likely," he told Big Brother.
