What amuses me is how people will sometimes volunteer the fact that they have some pretty intimate body piercings whenever they alarm the WTMD, and often with opposite genders (more women volunteer this information to male screeners). Reminds me of a cute little incident that occured when I was a contract screener. A male passenger alarmed the WTMD and boasted as he pointed towards his genitals that he had a piercing. The female screener intended to explain to the passenger that there wasn't enough metal in piercing alone to set off the alarm. But what she said instead was, "no, sir...it's not big enough."
