Anyone who has had the pleasure of using commercial air travel in the last few years knows what fun it can be.  Here's a helpful tip when you remove your belt buckle to go through the metal detector.  If your pants start to fall down, don't refer to yourself as a "Weapon of Ass Destruction".  This may cause you to experience a secondary inspection, which may include a pat-down and check with a hand-held metal detector, and possibly further delays.  Apparently the TSA requires their employees to have their sense of humour removed.  Fair warning.
