Disclaimer: Doctor Who belongs to The BBC and the song What's This was written by Danny Elfman for Tim Burton's The Nightmare before Christmas. I own nothing. This is just a parody to the tune of What's this?

Nightmare before Christmas's What's This... If Jack had found The TARDIS instead of Christmas Town...

:-P

What's this? What's this?
There's aliens everywhere.
What's this?
There's a spaceship in the air!
What's this?
I can't believe my eyes.
I must be dreaming.
Wake up, Jack, this isn't fair!
What's this?

What's this? What's this?
There's something very wrong.
What's this?
There's Ood singing songs

What's this?
The streets are lined with

Potato dwarves weapon crafting,
Every other Scifi show seems crappy.
Have I possibly gone daffy?
What is this?
What's this?

There are children playing with screw drivers
And there are monks without heads.
They're busy collecting Who Toys
And absolutely no stays dead!

There's creature out the window.
Oh, I can't believe my eyes.
And in my bones I come to know
That it's bigger on the inside.

Oh, look
What's this?
Harkness is Face of Boe!

And they kiss!
Why! That looks so unique.

Inspired!
Poor Amy and Rory..
Steve Moffat is a liar!
What's this?
What's this?

In here

They've got a police box.

How queer!
And who would ever think?
And why?

The controls are covered with tiny little things.
They've got electric lights on strings.
And there's a confused face on everyone.
So, now, correct me if I'm wrong.
This looks like fun!
This looks like fun!
Oh, could I stay inside this TARDIS?
What's this?

Oh my.

What now?
The companions won't stay asleep.
And look, there's monsters underneath.
Some ghouls, witches here to scream and scare them
Or ensnare them.

Even little Oozy things
Can reach inside their dreamland.
What's this?

The monsters are all missing
Because The Doctor has been found!
And in their place there seems to be
Jelly babies all around!

Instead of screams, I swear
I can hear theme music in the air.
The smell of custard and fish
Is absolutely everywhere.

The sights.

The sounds.
We'll go everywhere

And all

Around.
I've never felt so good

Before.
This empty place inside of me is filling up.
I simply cannot get enough.

I want it! Oh, I want it!
Oh, I want it for my own!
I've got to know!
I've got to know!
What is this place that I have found?
What is this?
The BBC, hmm...
