Mother:
If you give a mouse a cookie, he'll want a glass milk. If you give him some milk, he'll want more. If you give a mouse more milk, he'll develop a taste for human blood. If he develops a taste for human blood, he'll become a vampire. If he becomes a vampire, he'll have to make followers. Now, if he makes some followers, they'll need to feed. If they feed too much, the national guard will be called out. If the national guard is called out, they, too, will become fodder for the vampires. If the national guard fails, the President will call in a nuclear strike. If a nuke is dropped, hundreds of thousands of people will die. America will become a nuclear wasteland and collapse. With no one to keep the rest of the world's nukes in check, every crackpot nation will launch their own. Eventually the entire earth will be destroyed. And that's why I had to kill Daddy. He was giving a mouse a cookie. [laughs] Sleep well, sweetie.
