My favorite weapon is the McDonnal-Douglas ICBM with any size nuclear warhead, for household vermin, or small game hunting. I keep one armed by the front door.
For home defense, I usually use a Remington 12-guage, with 000 shot, or a 120 lb crossbow. Nothing says 'get out of my home' like 3" of an 8" bolt protruding from your sternum.
