In Hawaii at the moment, at Kona on the big island.

Flying here, I actually saw this, I swear to you:

A nice woman in her early 40s was asked to step out of the security line for what seemed to be a random pat-down.  The TSA employee patting her down went about her business, and then suddenly fixated on a small hard spot underneath the woman's shirt, maybe four inches below her left breast.

The TSA worker patted and poked this object several times, with an increasing look of concern.  

Finally, the screener asks: "Ma'am, what is this?"

"Oh, that?  It's nothing" the lady says.

The screener's radar goes up.  Time to call for backup.  "Ma'am, I need you to tell me what this is."

The lady pauses, looks the screener straight in the eye, and with a withering look I hope I never receive, delivered a full and complete explanation.

"That's my rib," she said.
