Top 10 ways you can tell you’re a forensic DNA scientist 10. You have your kid’s DNA types vs. their pictures on your wall. 9. When your kids were born, you got an extra newborn footstick smpl. 8. When your kids get injured you are more interested in collecting the blood than dressing the cut. 7. You have a backlog of fingernails, hair, and teeth from every member of your willing lineage awaiting testing. 6. You want to open a paternity service for the Jerry Springer show. 5. When you stay in hotels you bring a portable UV light so you can avoid unsanitary latent stains, and then you collect them. 4. You know forensic DNA takes longer than a CSI commercial break. 1. You see stains where no one else can. 2. You spend your day looking at dirty underwear. 1. Your license plate reads “ OJ DID IT!” * Modified from Butler, J. 2005 ACS Meeting presentation
