ETA: Steven Moffat explains a bit more to SFX
“Two episodes. Two mini-episodes. Very, very small episodes – maybe eight minutes in total, so that’s around four minutes each. It’s not a spoof. It’s in the style of the ones that we’ve done for Children In Need, so it’s taken seriously as a proper bit of Doctor Who – funny, but not a sketch. A little miniature story. One’s called ‘Space’ and one’s called ‘Time’, so they’re Space & Time. And there’s a moment with two Amy Ponds in it. If you’re a red-blooded male surely that’s enough! You’ve got Amy Pond flirting with herself.”
The TARDIS inside the TARDIS???? It blows my MIND!!!!!!!
That's what I was thinking! Almost word for word actually.
"You’ve got Amy Pond flirting with herself."
