Drew and Timmy were brothers. One day Mom and Dad had to go into town. Dad told Drew, "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 Drew, "What have you been doing while we were gone?"
Drew replied in a low voice, "Nothing."
Dad then turns to Timmy and asks, "What have you been doing?"
Timmy replied, "Helping Drew."
