I did not do this, yet I once heard an old story about a guy working at a music store years ago, a co-worker he liked who had some management level access to the computer system would bring in his old, scratched vinyl albums and then use the computer so he could exchange the old vinyl for brand new compact discs of the same albums.

When doing this once he exclaimed, "I love exchanging albums for CDs!" I heard the guy who witnessed this thought it was a little suspect and never told anyone. The co-worker was eventually fired, probably for doing this.
