Unlucky numbers as a nation.

[Bigoldowls]

Here in the UK we have some numbers which, via superstition, are deemed unlucky or unfavourable. These numbers are 111, 222, 333, etc. They are also known as 'Nelson', i.e., 111 is 'Nelson', 222 is 'Double Nelson', 333 is 'Triple Nelson', and so on. I know that in Australia the number 87 is thought of as unlucky. Are there any other nations which have unlucky numbers?
