This is my idea, it may be a bit crap but here goes.
The idea is that the HM's have to recreate each other's original video applications for the show. So this wud involve them all having 2 know wot each one did in their vid. Then, Big Brother calls a HM at random and asks them to recreate the events which occurred in another HM's vid.
This wud range from Jonny falling over in the street in wot appeared 2 b a big puddle, to Alison's rather resourceful "Here's wot's in my handbag" to um... Lee's stripping off. I think possibly Kate or Sophie shud be asked to re-enact this one.
I really wouldn't have a clue as to how to e-mail this idea 2 the powers that be at Channel 4, so if sum1 else can be bothered if they think it's a good idea, then go ahead.
