Basically just try and imagine you are flicking through the channels of a TV and each time the first programme seems to lead into the next one with a humourous result!
So I would post the first programme, the next poster the next etc.
E.G.
"...today on Blue Peter we are going to take some toilet roll tubes, some glue and some sticky back plastic and build...."
*click*
"...Weapons of Mass Destruction. Today Tony Blair said in a statement that..."
Get the idea?
OK, I will start,
"Today Tony Blair said in a statement to the worlds media..."
... before emitting that plaintive cry 'I submitted too late! I submitted too late! It's not fair! It's not fair. The world's against me! The world's against me!'
