1. Knock wife unconscious.
2. Drag wife downstairs to car, place in car, pour a bottle of jack Daniels down her gullet.
3. Start Car, place car in drive.
4. Pour flammable liquid over front of car and light match.
5. Close garage door and walk away.
6. Get some sleep as it has been a rough day.....
