I used to work for TSA and spent a couple years working at the international checkpoint. This is where people who flew in from other countries would go through security before continuing on to their connecting flights. Once we had a lady come up and, while she was taking off her coat to put it through the x-ray, the person running the metal detector noticed her left breast was moving very erratically, and very awkwardly asked what was causing that. And the lady gave a deep sigh, rolled her eyes, and said "It's just a turtle," and she pulled a tiny baby turtle out. We had to call the customs people to come get her, since animal smuggling is pretty illegal.

Her eye roll though when she said "It's just a turtle..." Like that is a normal thing to have in your bra.
