Prosthetic Body Parts Photos Keep this

After reading Mad Dog's article about eye-patches I was inspired to come up with another obvious category. Throwing back a nod to Ancient of Mumu with the calendar concept.... or a top 1.  My criteria used to winnow it down to a dozen was... movie or TV but no anime/cartoon/comic... only humans. It's not so much about the character as it is about the body part... has to be cool and preferably it has uses beyond what nature intended. Many of the characters in this article have gone on to become memes and have been mocked, copied, or otherwise been paid homage in other movies. Sci-Fi is liberally applied as I wanted to keep the title consistent with the original.
