Oh, I have a friend in high school who had this but between her fourth and pinkie toes. I always thought it was neat but most of our teachers thought it was "unsettling". :/
As for myself, the only things I have pierced right now are my ears and lip (snakebites, naturally) but I'm thinking of getting the bites redone since they're pretty low on my lip.
Right now the ears are at 00g circular barbells but I used to have them at 5/8 in. until I blew them out sizing up, had them at this size for about five months now.
