One time I went to the lost and found at school and told them I lost a dollar. So the lady asked me when I lost it and I told her it was a day or two before and she went back behind the counter and pulled out a daller. I guess some girl had found it the day before. I felt a little bad because I hadn't really lost a dollar but I was also really suprised it worked ...oh and this was 10 years ago too.
