Shhhhh, don't tell anyone, but I am actually the Rani in disguise. (You're not supposed to know that until the season finale.)

Amazing TARDISEdit

Look at my TARDIS, my TARDIS is amazing.
Give it a lick. "Hmmm, it tastes like it's ancient!"
Put your hand on this pane, she turns into a plane.
Then turns back to a time machine if you insert your pinky.
"Oooo that's dirty!" Do you think so?
Well, then I'd better not show you where screwdrivers are made.
Screwdrivers, sonic screwdrivers.
Screwdrivers, sonic screwdrivers.

Get in the doors, I'll take you 'round the universe,
And all the other places, too.
"I think you'll find that the universe pretty much covers everything."
Shut up Romana, get in the doors.
