The OUTside.
Now, you might say the outside wins due to feathers that have been plucked or fallen out, which obviously are not inside the turkey, altering the balance.
This leads me to ask an important to settle this debate once and for all. Are there quills that have started growing inside the turkey, yet have not yet made it past the skin? Could these be technically considered feathers? If so, are there enough to account for those feathers on the outside only by virtue of the fact that they have fallen out or been plucked? These are all important questions.
Another question that has never been properly settled for me: How many licks does it take to get to the center of a Tootsie Roll Tootsie Pop?
