Ok, being on the nasty topic we are one, I'll share one of the nastiest experiences I ever had in a pool.
I was swimming around (obviously, I was in a pool) when something floated and touched my face. I looked down and saw a blood bandaid! It was sooooooooo nasty >_<
Oh and recently here in Sweden, a family found a chopped off thumb in their bag of shrimps!!!! The company are guessing that a worker got his/her thumb cut off in the machine that sorts the shrimps. Naaaaaaaaasty...
Hope I didn't gross you guys out too much
