Dressing up as food is a sketchy proposition. Not that you should be afraid that you'll find yourself on a desert island and one of your fellow survivors will look at you and imagine you as a giant turkey meal, but you should be more afraid of walking into the bathroom, looking in the mirror and thinking "Man, I could really go for a whole turkey." But then where are you going to get a turkey in the middle of the night?
The Lightweight Adult Turkey Costume might be a delight, but it also might be a double-edged sword. It's something to consider. Gobble gobble.
