1. My Legions of Terror will have helmets with clear plexiglass visors, not face-concealing ones.
2. My ventilation ducts will be too small to crawl through.
3. My noble half-brother whose throne I usurped will be killed, not kept anonymously imprisoned in a forgotten cell of my dungeon.
4. Shooting is not too good for my enemies.
1. I will maintain no association with sidekicks who employ prostitutes. While such entertainment doubtlessly relieves my comrade of the wearying burden of the Heroic Struggle, the women met in this fashion tend to filch artifacts needed to defeat the Evil Overlord, act as his spies and/or assassins, carry unpleasant diseases, and (worst of all) get me in trouble with my True Love.
2. I will ignore the Evil Overlord's arguments revolving around honor and/or morality. If he were really all that worked up about either, he would never have become an Evil Overlord in the first place.
3. When the Evil Overlord takes hostages, I will presume the hostages dead and hold a memorial service. Any promises made by the Evil Overlord regarding their safe return shall be summarily ignored. My loved ones will be warned to expect this.
4. I will not walk alone and undisguised into a bar in the Evil Overlord's territory in order to meet with an ex-associate who said a bunch of damaging things about me in one of the Evil Overlord's propaganda pieces.Link
