How do you properly cook a turkey?

Put that sumbitch in the oven....

There are clearly many variations but basically roast in at about 350˚ for about 20 minutes per pound.

Put on an oven mitt, stick it up the bum, have your kids use heat guns to cook it while you hold it out at arms length. Put your husband on stuffing duty. He's been bad. He doesn't get ANY.

Always watch it while cooking it.

There is no proper way. The internet has hundreds of methods.
