1. Dry livers and roll in flour mixed with salt and pepper.
2. Cut each bacon slice in 5 pieces. On 3 bamboo skewers alternate bacon pieces with livers, skewering livers through thickest parts.
3. Place on broiler pan. Broil 4 inches from heat, turning and basting frequently with butter. Broil until bacon is crisp and livers are browned outside and pink inside, about 5 minutes per side.
