Earl Sigma quotes from Doctor Who

Name?

I'm the Doctor. Haven't we met?

I'm sorry, that's classified information.

You're Trevor Sigma, aren't you?

Galactic Census Bureau, I ask the questions.

You ask the questions?

I'm sorry, that's classified information. Address?

Which one?

If you live here, I need a town and a street. If you're an alien, I need a home planet, except when you spend more than half the work year away, in which case I need a planet of origin.

That's classified information. Name?

What?

I ask the questions. Name!

Trevor Sigma.

Address?

Galactic Census.

What's happening Doctor?

Questionnaire. Occupation?

Galactic Census Bureau, authorised to enter all Alphan property and to interview all Alphans.

Good, take me to your leader.

You're a nice guy Doctor, but a little weird.

Blissful, isn’t it, Doctor? Silence.

Aha, not quite. I can hear the sound of empires toppling.
