(He's very tall for a 13 year old

)
Actually, just out of interest, how tall are you?
Nice filler screen, all it needs now is a girl with a blackboard, some chalk and a doll. Perhaps that Dalek should have a bit of chalk (or a board marker) stuck in it's gun with it saying "My cross has exterminated your chances of winning^!".
Maybe...
The ^ symbolises a rise in pitch in the Dalek's voice...yes, I actually imagine them saying it as I type it.
