James and his wife, Martha, are getting ready to leave home for a vacation.Martha started out the door, then stopped, turned around, and said, “James, this time you should go check to see if the coffee pot is off, television plugs are pulled, lamp timers are set, thermostat is adjusted, windows are closed and locked, burglar alarm is on, doors are locked, and I’ll go wait in the car and keep blowing the horn.”
