Teacher asks the children to discuss what their Dad's 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.

Teacher says: "Johnny, what does your Dad do ?"

Johnny says: "My Dad is dead."

"I'm sorry to hear that, but what did he do before he died ?"

"He turned blue and shat on the carpet."
