Game of Thrones, Season 2

Tyrion Lannister:
It's just you, me and Joffrey, the "Lord of the Seven Kingdoms and Protector of the Realm".

Cersei Lannister:
I'm sure you'll make a point eventually.

Tyrion Lannister:
He needs to start acting like a king! This war you started is coming to our doorstep and if the entire city wants Joffrey dead...

Cersei Lannister:
I'm not the one giving the boy whores to abuse!

Tyrion Lannister:
I thought the girls might help him.

Cersei Lannister:
Did you?!

Tyrion Lannister:
I was wrong! If we can't control him-

Cersei Lannister:
Do you think I haven't tried?! He doesn't listen to me!

Tyrion Lannister:
[nodding] It's hard to put a leash on a dog once you've put a crown on its head.

Cersei Lannister:
I always hoped he'd be like Jaime. He looks like him, in a certain light.

Tyrion Lannister:
The boy's more Robert than Jaime.

Cersei Lannister:
Robert was a drunken fool, but he didn't enjoy cruelty. Sometimes, I wonder-

Tyrion Lannister:
What?

Cersei Lannister:
If this is the price for what we've done. For our sins.

Tyrion Lannister:
Sins? The Targaryens-

Cersei Lannister:
Wed brother and sister for hundreds of years, I know. It's what Jaime and I would say to each other in our moments of doubt. It's what I told Ned Stark when he was stupid enough to confront me. Half the Targaryens went mad, didn't they? What's the saying? "Every time a Targaryen is born, the gods flip a coin."

Tyrion Lannister:
[awkwardly] You've beaten the odds. Tommen and Myrcella are good, decent children, both of them.
