Friday 13th., watch out – glass eye:
Friday 13th. is not over yet, take care and keep your eyes open.
I met an Englishman  at a diving safari in Burma and he was a crazy collector of rare things. He told me some weired storys and one of them was that he asked at the coroner at a hospital if he got glass eyes. He got not just one, he gave him a full box of them. Needless to say, I had to get at least one. They are true masterpieces of craftsmanship and quite expensive even 2nd hand.
