Definitely A, it would take my pirate costumes to the next level.

At this point in medical history I don't think I'd mind losing a leg if I could get one of those bionic spatulas, but I would comb my hair with a shotgun sooner than later if I lost an ear. When I get sick and have even a partially clogged/shitty ear it makes me want to dive off a cliff; couldn't imagine the permanent deafness on one side.
