What would Jack do about HEALTH CARE?

If you chose (A) give yourself a seawater bath. Jack is blithely unaware of the state of his teeth but he would never do 'nothing.'
In choice (B), the question is What's In It for Jack? Prepare to feel the sting of the 'cat.'

Selection (D) has potential, but Elizabeth has no butt. Jack also would never dole out coin for Barbossa's hat and stealing one is another story. Demote yourself to swabby, you dog.

The correct answer is (C): Gnaw a bullet out of his own leg, splash some seawater on it, and then pillage Tortuga. While it's unlikely he would pillage a pirate haven, we must assume he has a reason. By gnawing the bullet out of his leg Jack is taking care of his health needs. Promote yourself to mate.
