In addition to some flavorin's under the skin, injecting the bird is a nice addition. Butter+Beer+creativity is a good place to start. Cook it for around 3.5 minutes/pound. Oil temps need to be closely monitored after you drop the bird.
But for sure, safety is key. Pat the bird dry to an obsessive amount, and let it sit at room temperature for as long as (safely) possible. Wear good gloves and lower it very slowly into the oil.
