I regularly visit a few places that require visitors to undergo a bag scan (like the scanners at the airport.) I am, therefore, familiar and friendly with the guards.
At one place recently, my jewelry set off the alarm, so one guard used the wand to inspect me. While he was showing me which pieces of jewelry were making the wand beep, his friend over at the X ray machine said, "So, it's not these handcuffs in your bag."
I thought the guy was making a joke, so I said, "No, it's not my handcuffs," and I gave him an exaggerated wink.
He said, "Can you show me how they work?"
I was amused but surprised because these guys are usually a little conservative, so I laughed and said, "Sure, but not during work hours." I think his colleagues thought this was a joke, too, because we all chuckled.
He persisted, "But I see something round in your bag. How does that work?"
Then I realized what he was seeing. "THAT!" I exclaimed. "You must not be married. It's a purse hook. All the ladies carry one."
I took it out and demonstrated how it hooks the purse to a table top or chair back. It really would make the prettiest handcuff.
We al had a good laugh, and before I left the screening area, the female guard said, "Next time you come back, put a feather boa in your purse."
