If you really want to gross out the metal detectors and security at airports, get yourself a few piercings!! A friend of mine travels a lot, and has multiple piercings including a 'Prince Albert'..... they get very worried when he has to put THAT on the tray.......

His wife is ..... similarly pierced. She just gets waved through when he explains..... you don't want to mess with a guy who voluntarily had THAT done to his ooHOOhoo..
