Would it be wrong to stuff a pre-roasted Cornish game hen inside the turkey, then at dinner tell all the kids, "Uh-oh, it looks like we cooked the turkey's baby, too!" while you pull it out?*
And if you make a turducken with tofurkey in it, is it... No, I can't bring myself to complete that.
Happy Thanksgiving, everyone. Cook your turkey thoroughly.
