When my dad was a kid there was a stray dog who used to pal around with him and his friends. As my dad told it, when he'd come home from school the dog would always jump up and throw his paws over my dad's shoulder to give him a hug Hello. One afternoon, the dog missed by an inch or two and wound up scooping out my dad's eyeball. Dad didn't freak apparently and just trotted himself on into the house while cupping his still attached eyeball up under its socket in his hand. His mother however, freaked (understandably). Off they went to the doctor, the eyeball was popped back in, his vision wasn't affected, and we always had a way of detecting when he was sleepy -- his eye would start to droop a little bit. (And in a sad twist, my father actually lost his vision in his other eye many years later. But that's another loooooooong story).
Bodhi can be somewhat curious when she wants to and particularly enjoys exploring our world through her sense of smell. She's a hound and sniffs her way through life. A friend and I were taking her for a walk when she was a little over a year old and we came upon a VERY old man and his VERY old dog. They appeared to be in an unspoken race to see who could decay faster. One of the dog's eyes was all dead and shriveled up in its socket and as Anne and I were talking to the old man, Bodhi began sniffing the dead eye. That was bad enough, but I guess she was confused by what she smelled, because she then stuck her tongue onto the eyeball to investigate further. She loves dead things, so I'm guessing she was just trying to figure out what was going on. I like to imagine Bodhi's thought process... "You smell dead. Are you dead? Do you taste dead? Blep." I embarrassingly pulled her away from the poor dog and was relieved to realize that the old man was so nearsighted that he hadn't seen what happened.
