Doctor Who: Flatline
The Gabby Gallifreyan was in full swing in "Flatline."
Clara takes on an alien menace while the Doctor is dying in a shrinking TARDIS. But this sketch is really about the speech that poor Peter Capaldi had to deliver while banishing the Boneless in the 2014 Doctor Who episode "Flatline":
"I tried to talk. I want you to remember that. I tried to reach out. I tried to understand you. But I think you understand us perfectly. And I think that you just don’t care. And I don’t know if you’re here to invade, infiltrate or just replace us. I don’t suppose it really matters now. You are monsters! That is the role you seem determined to play. So it seems that I must play mine! The man that stops the monsters. I’m sending you back to your own dimension. Who knows? Some of you may even survive the trip. And if you do, remember this: you are not welcome here. This plane is protected. I am the Doctor. And I name you…the boneless!"
Moffat never met a speech he didn't like.
