What is it? I once did dishes in the bath tub when we let the dishes go once. We were having a busy week and barely home, so most of our dishes were dirty and there wasn't enough room in the sink. Bath tub was bigger. Scrubbed the tub and disinfected it first, but... :/
I've swallowed a fly by accident, it was horrible.
I had to pull off my own nail as I'd previously had an accident where it got very bruised and if it didn't come off my new nail wouldn't grow.
I used to twist out my loose teeth.
I try to avoid gross things. I always drop food in my house and eat it anyway though, which I guess is gross. I'm too greedy and clumsy to let it bother me.
