Tinker Tailor Soldier Spy

"It'll take us five hours to get drunk on this monkey's piss!"
[As he is going to pour vodka into the punchbowl at a party]

Connie Sachs: "It was a good time back then."
George Smiley: "It was a war, Connie."
Connie Sachs: "A war we could be proud of."

Control: "All I want from you is one codename: Tinker, Tailor, Soldier ..."
George Smiley: "... Spy"

"There's a mole, right at the top of the Circus. And he's been there for years."

Ricki Tarr: "They're going to kill me."
George Smiley: "Who is?"
Ricki Tarr: "Your lot. Or their lot, whoever gets me first. I'm innocent. Within reason."

George Smiley: "Is there anything you would like me to pass on to Ann?"
Bill Haydon: "That was nothing personal, George. You have to understand. Karla said that you were good; the one we had to worry about. If I were to known as Ann's lover, he'd figure that you wouldn't be able to see me straight. And he was right, up to a point..."
George Smiley: "Up to a point."

"As I said, you may f*ck me but you still have to call me 'Sir' in the morning."

"It's the oldest question of all. Who can spy on the spies?"
