A Teacher asks the children to discuss what their fathers do for a living. Little Mary says: "My Dad is a lawyer. He puts the bad guys in jail." Little Jack says: "My Dad is a doctor. He makes all the sick people better." All the kids in the class had their turn except Little Johnny. The teacher says: "Johnny, what does your Dad do?" Little Johnny says: "My Dad is dead." "I'm sorry to hear that, but what did he do before he died ?" "He turned blue and shit on the carpet"
