Literally the setup for the final boss of Yakuza 4
Daigo: Finally, with this money I can rebuild the Tojo Clan. But you knew I’d say that, huh...Arai?
Arai, stepping out from behind the money: It is as you said, Chairman. I knew you’d say that, but it seems that you knew I knew that you would be here. But it seems you didn’t know that I knew that you knew I would betray you, which is why you turned my own man against me. Isn’t that right...Kido?
Kido, stepping out from the other side of the money: Sorry, sir, but it seems you knew. You’re right, the Chairman knew that you would betray him.
Arai: I knew it. You see, me knowing that the Chairman knew that I knew that he knew that I would betray him led me to keep you alive to confirm me suspicions.
Kido: It was a good plan, but we knew that you knew that we knew that you would betray us, and so now we outnumber you.
Arai: You almost had me, and it seems that even though I knew that you knew that I knew that you knew that I would betray you, I am now at a disadvantage. But, unfortunately for you, there is something neither of you could know (Arai pulls out his badge).
Daigo: You’re a cop?!?
Arai: That’s right! In the end, I came out on top!
Munakata, climbing out of Arai’s coat pocket: You utter fools! You complete idiots! You spent so much time squabbling among yourselves that none of you knew that I knew of all of your plans! Now I can betray you all!
