Turn Your Kilt Across Your Tummy

Interesting post.
As for incorrectly calibrated detectors, I once had one go off everytime I went through, only metal objects were my buckle, zip and watch, and even with watch and belt taken off it still set off the alarm, and joked to the security team that it'd probably still go off I went through naked.
They weren't impressed, but finally let me through.
