Have you had an unbelievable coincidence like this?

I had a friend in college who always referred to a guy almost in irritating frequency. Years later I went to a job interview where there were 30 persons. I was selected so was another fellow. I got into a conversation with the chap and guess who he was. Yes the same guy who my friend was always speaking about. Of the 30 guys present there, we two had to meet. What a strange coincidence!
