Please make sure to listen to Selkies advice and do NOT use flour or wet the area around the fryer. Both of those practices are extremely dangerous and could result in death.
This is a great post. It is a number of years old, but the information is still great. Take a look. The 10 Commandments When Frying Turkey.
Don't talk your husband out of doing it. Do make sure he is educated in proper technique and safety first though. Make sure to cook it away from the house. Make sure you have safety equipment close by (fire extinguisher rated for oil fires, heavy heatproof gloves, proper clothing that is not loose fitting, phone to call 911, etc.). Even the smallest drop of water can cause serious problems so make sure the turkey is dry dry dry before it goes in the fryer. GO SLOW. Do NOT drop it into the pot. Lower it very very slowly. The oil will bubble up as soon as the turkey hits the oil. Put it in slowly so oil does not splash out. Do NOT be drunk when doing this. Thanksgiving is a great time to knock back a few, but you do not want to be tipsy when doing this. If you are not OK to drive a car then you are not OK to fry a turkey.
