Ready whenever you are! I'm not the best starter though :P
One Two Three Four I declare a time war
Five Six Seven Eight Daleks scream "EXTERMINATE!"
Nine Ten Eleven Twelve The Doctor died and Silence fell
Twelve Eleven Ten Nine There he goes back in time
8 7 6 5 Saving everybody's lives
Four Three Two One Grab her hand and whisper"Run"
This post could be a bit more SONIC, you think?
