One day, Satan comes to a church. Everybody in the church is afraid and runs away. Only one old man stays in the church.
So Satan walks to the man and says, “Do you know who I am?”
The man says, “Yes, I know who you are.”
“Aren’t you afraid of me?” Satan asks.
“No, I am not.” says the man.
“Do you know that I can make life horrible for you?” asks Satan.
“Yes, I know,” says the old man.
“Do you know that I can kill you with one word?” asks Satan.
“Yes, I know,” says the old man.
“And you’re still not afraid?” asks Satan.
“No,” says the old man.
Satan is shocked but asks, “Why aren’t you afraid of me?”
The man says, “I married your sister 48 years ago.”
