Doctor: When you find something brand new in the world, something you’ve never seen before, what’s the next thing you look for?
Strax: A grenade!
Strax: Sir, permission to express my opposition to your current apathy?
Doctor: Permission granted.
Strax: Sir, I am opposed to your current apathy!
Strax: Sir, do not discuss my reproductive cycle in front of enemy girls. It’s embarrassing.
Strax: Sir, emergency! I think I’ve been run over by a cab!
Strax: Do not attempt to escape or you will be obliterated. May I take your coat?
Doctor: What are you doing here?
Strax: Madame Vastra wondered if you were needing any grenades.
Doctor: Grenades?
Strax: She might have said help.
Doctor: Help for what?
Strax: Well, your investigation.
Doctor: Investigation? Who says I’m investigating? Do you think I’m going to start investigating just because some bird smiles at me. Who do you think I am?
Strax: Sherlock Holmes.
Doctor: Don’t be clever, Strax, it doesn’t suit you.
Strax: Sorry, Sir.
Doctor: I’m the clever one. You’re the potato one.
Strax: Yes, Sir.
Doctor: Now go away.
Strax: Yes, Mr. Holmes.
Doctor: Oi, shut up! You’re not clever or funny and you’ve got tiny little legs!
Strax: *giggles*
Me: IT’S A GIGGLING POTATO!!!!
Strax: Suggest we melt his brain using projectile acid-vision, then interrogate him.
Vastra & Jenny:
Strax: Other way round…
Strax: This dwelling is under attack. Remain calm, human scum.
Maid: *screams/faints*
Strax: Sir, please do not noogie me during combat prep!
