About a month ago when I was flying, I accidentally left a tiny screw in my pocket from a piece of equipment I was servicing. I was of course flagged when I went through for a pat-down. After going through the scanner, I found the screw in my pocket, and showed it to the TSA agent. I was wearing Levi's 511 jeans and a tucked in shirt, but was going commando. He still did the pat-down despite showing it to him. He checked my waistband by pulling out my jeans and running a finger around them. He then did this in the back, and then came back and did the front again and sort of hesitated. Not sure if he was surprised not to find any underwear, or if he got a vantage poinit where he could see down my jeans when he pulled them out and was able to see down them to what they contained, but I found it odd he spent a little more time on my waistband than typical....maybe he was looking for a Prince Albert?
