Food - Pizza, everybody loves pizza (or, one of my casseroles).
Garment - a comfy t-shirt, who wants to hang around in a closet all the time?
Appliance - oven.
Room - kitchen, good things happen in kitchens (or one of your quieter tap rooms).
Illness - tonsillitis, maybe. I don't want to kill people. Not most of the time, anyway.
War - War on drugs. C'mon, now, who's surprised by this one?
