Banned, because you must be against eating a vegan and a meat-eater together.

Banned because as a fellow knight, I can't let you speak something as outrageous as thinking that cannibalism is okay. I'm sorry, but I need you to return to your chamber and be locked there for five days while also contemplating and reflecting on what you had said!

(Dang it. With le_chevalier currently under chamber arrest, the castle has been weakened quite greatly with a skilled swordsman such as him being taken out of duty for a while)

Banned for telling everyone about the weakened castle.

Banned because I didn't know that apparently everyone can hear what's going on inside my head.

(Shoot, he's right. I need to suspend le_chevalier's punishment right away before the undead army can be seen marching on the horizon)

Banned for trying to suspend a punishment without going through the proper channels.

(I hope thinking aloud is not contagious. Those knights must never know that the undead army is about to replace them. They work for a mere fraction of the wages of those knights and they aren't even unionized...)

Banned because this is an emergency! You as the king should know this better. If we lost this castle, you'd be forced to flee with the risk of getting caught during your escape to a neighboring kingdom.

(Too bad, I could hear what you were thinking. I will warn the other knights and invite them to start a small rebellion against you before the undead army arrives, hoping that the rumors of this act will spread fast and incite a bigger rebellion together with the other knights stationed in the other fortresses. If this could end quickly with you being overthrown from your royal position, then we might just be left with enough time to send a messenger to the advancing undead army and demand them to fall back as the deal would no longer hold any validity)

Banned for suggesting that these knights are not undead already, although they are.

(But they are good quality, which explains the incoming other-undead army...)

Edit: banned for ninja'ing me.

Banned for suggesting that undead can be knights, they may only be former knights.

(I wonder how one could accurately describe the undead after they are killed... are they the dead undead or undead dead or perhaps deceased undead. None of this makes any sense... oh, toss it all.)

Banned because you're right! However, as you know, I need to ban you in order to communicate with you no matter of whatever opinion I hold against your statement. (Which I agree)

*hears a groaning sound coming from the chamber that I had locked le_chevalier in* What the? *hastily looks inside the chamber through the small hole at the top of the door, only to see le_chevalier turning his head over his right shoulder in a manner that no normal human being would do it* W-what happened to your face? *le_chevalier's staggering movement accidentally knocks over a lantern on a desk next to him to the ground, causing a fire that slowly illuminates le_chevalier's whole upper body and finally revealing his face that no longer resembles human* Y-you're an undead?!

(I think they would be called dead undead. But like you said, toss it all! Anyway, it's quite interesting to know the kind of questions that wizards often ask themselves daily in their spare time)

Banned for contradicting yourself agaisn't your own opinion, defending your own argument agaisn't yourself?

(Am I really reading what other people around here are thinking, or am I a Jedi or something?)

Banned, because Sir Vingry (former Sir Verlam) is not the knight you're looking for.

(Whoa, the mind of D.Keys is a disconcerting place to visit.)

Banned for not telling who the knight D.Keys is looking for is.

(Unalive? Nah, that sounds bad; Ultra-Dead? Even worse. I will call them dead undead.
Ouch, I thought that damned knight who bit me was still banned? Hm, I'm getting hungry. Steak? No. Some sausages? Bah. Braaiiiinnzzzzzzz!!!!)

Banned because everyone's putting really long bans now.

@MightyFloTheKing
Banned for failing to pass your statistics class.

@HMA
Banned for ninjaing me and wanting short bans.

Banned for banning multiple people in one post.
