Godot: "…Add the pureness of milk to the perfect, clear darkness of coffee. Stir. That is the state of the witness’s mind right now — a cup of café au lait."

Judge: "C-Café o’ Lay? Is that even legal…?"

Godot: "Mr. Trite’s words are the milk and you are the spoon, Your Honor."

Judge: "I-I'm a spoon!? I'm no spoony bard, I'll have you know!"

This. Sentence. Is. FALSE.
Don't think about it, don't think about it!
Um, true. I'll go with true. There, that was easy. To be honest, I might have heard that one before.
It's a paradox! There IS no answer.

I AM ERROR.

1. Do you realize how that made me feel inside? FURIOUS! OUTRAGED! SICK WITH ANGER!
2. In truth, I much prefer to be indulged with my full title: Lord Ghirahim.

Maximo ps2

Achille: "General!"

Skeleton General approaches.

Achille: "Your orders were to kill Maximo,"

The general, whimpering, begins to run away from Achille. Achille releases some purple charge from his staff towards the general

Achille: "So here is your reward."

The General is hit by Achille's projectile, and this causes him to regain his blood, muscles, and then flesh.

General: "I'm alive!!"

Achille: "Guards!"

Two skeleton guards approach.

Guards: "Yes my lord!"

Achille: "Take the general away and torture him, until he dies."

The two guards close in on the cowering General

Achille: "Maximo! Your fate will not be so pleasant."
