Does anyone remember Shattered?
 

It was like Big Brother but the housemates weren't allowed to sleep and had to do tasks that would usually make them sleepy; having a massage, cuddling a hot water bottle and being read a bed time story.

That was brilliant!
Dermot O'Leary presented it, I remember because he proved himself to have trouble with his script constantly tripping over words and repeating himself.

Does anyone remember it?

yes

Yes, I could never remember what it was called.

I found it on 4oD!
Why didn't they make another series?

I remember it but I never watched it, I might give it a go when BB is over if its on 4OD
