A man broke into a jewelry store in the middle of the night. Once inside he broke the glass case to extract the jewelry -- so excited and anxious to get his hands on the diamonds in the case he did not notice, that when he broke the glass, with his hand, he cut the tip end of one of his fingers off. When police did arrive, they merely fished the top portion of the finger out, printed it, and ran a match program. The man was arrested within a few hours of his crime.
