Doug and Jason were brothers. One day, Mom and Dad had to go into town.
Dad told Doug, "While we are gone, I want you boys to clear away the dirty dishes, clean your room, and mow the grass."
When they returned, nothing had been done. Dad was very upset. He asked Doug, "What have you been doing while we were gone?"
Doug replied, in a low voice, "Nothing."
Dad then turns to Jason, and asks, "What have you been doing?"
Jason replied, "Helping Doug."
