Jack's Prosthetics is a prosthetic shop appearing in Grand Theft Auto: Vice City in the year 1986. It is located in Ocean Beach and is owned by a unknown man called Jack. The shops slogan is "It won't cost you an arm or a leg," and the store is currently advertising "Big nose sale now on."
According to myth hunters, Jack is rumored to be involved in the purchase of Human Organs from Romeros in Little Haiti and it has been speculated that the organs might be transported from the Romeros to Jack through R. S. & L. Bows. All these facts are however subject to speculations and aren't confirmed to be true. The shop could be a reference to surgery and facial transplants mafia leaders undergo in order to change their appearance.
