I came home yesterday to find a very official looking letter in the mailbox, which had originated in Switzerland. I'm in Australia, I don't know anybody in Switzerland, and have never had any form of business dealings with any Swiss company.
As you may suspect, the first thought that came to mind was "oh crap, it's a letter from some lawyers threatening me with some sort of legal action for buying counterfeit watches". With some trepidation, I opened the envelope to find... an annual report from a company I've never heard of and have certainly never had any dealings with. Riiiiiiiiight.
By the way, the envelope wasn't addressed to me by name, but obviously had my correct address on it. Very, very odd I say!
