I think I’ve told the story of (pre 9/11) forgetting that I had a package of guitar strings (coiled up wires, essentially) and an old metal alarm clock in the pocket of my coat one time coming back from Europe. Got their attention, though they didn’t do anything other than examine them closely. Yes, I’m an idiot. Not sure *what* would happen in this day and age.
*snort*
That’s a good one.
