I can picture the scene -
Doctor "Good morning gentlemen, we're just reviewing our list of people who need eyeballs replaced. Can you explain how you lost your eye in the first place so we can work out which one of you should get a replacement? P.S. I am a doctor."
"Well doctor, I lost my eye in a horrible...um explosion when I was on peacekeeping duties in the former yugoslavia. See I rescued this puppy, but it turned out to have a grenade inside. I shan't go into details but suffice it to say that when I picked the puppy up the pin was pulled and it went off."
Doctor "I see, and you patient #2
?... I have no bedside manner and cannot be bothered even making up names for you people"
"Well, I got this thing done in a piercing place where they slit open your eye and slide some metal in under the membrane"
Doctor "I see, well you both make compelling cases but ultimately, patient #2
- we're taking your other eye and giving it to patient #1
. You will spend the recovery time in our special 'room O' wasps'"
So yeah, you can get an eye replaced, but not if you explain how you lost the damned thing :)
