Ghost in the Shell: Stand Alone Complex, Season 1

Laughing Man:
I'll tell you. It was a simple piece of mail I stumbled across on the net that began the whole thing. What I'd found was a blackmail document that had probably been sent to Serano Genomics. It was armed with a thesis that was a comparative of the inadequacy of Serano micromachines versus the effectiveness of the Murai vaccine.

Motoko:
Then the original Laughing Man was the person who authored it?

Laughing Man:
You could put it like that, I suppose. "I am the machine that reveals the world to you as only I alone am able to see it"

Motoko:
Dziga Vertov. He was a Russian filmmaker, wasn't he?

Laughing Man:
Yes. I was kidding myself by thinking it was my personal mission to prove and circulate that information, vital data I alone had happened upon.

Motoko:
Failing spectacularly. The pure innocent mediator grew dejected at the base nature of the social system and he turned mute.
