Believe it or not, I was at church when I thought of this.
The Doctor marched forward with Rose in tow. "See this?" He said pointing to the cybermen."I thought you said you wiped them out of our universe."
"Not yet I haven't, but I will," saying that, he pulled out a small white rectangle ou of his long brown trenchcoat.
"Its that what I think it is?" Rose asked confused.
"Yep." Turning to the nearest cyberman, he slamned it down on the chest plate and fused it there with a flick of his screwdriver. "There you go, have an upgrade." The Doctor pressed a button on his screwdriver and yelled at Rose, "Cover your ears as tight as you can!"
A few seconds latter she saw all the cybermen running around banging their heads on the walls. A few had their brains attempting to crawl out their 'ears'. Then the heads of every Cyberman exploded.
The Doctor checked to make sure the coast was clear. "Come on Rose," he said tapping her lightly on the shoulder, "Lets go."
Rose asked the Doctor, "What was that?"
He turned and looked at her, a hint of fear in his eyes. "Oops, I did it again."
"You don't mean... her?"
"Yep. Her."
I do not own Doctor Who, Rose, The ipod, cybermen, or Britney Spears. I'm sorry if I offended all you Britney lovers out there. I make no money off this, so don't sue.
