Like small children, you could argue that seriously old people deserve a "free pass" through airport security. But just when you think that suspender-wearing grandpas are nothing but harmless coots, some old guy tries to shuffle through airport security with a knife strapped to his walker.

Yes, TSA officers at New York's JFK airport spotted a silver knife surreptitiously stowed against the legs of a walker back in 2012 [source: Burns]. Upon close inspection, the weapon looks more like a long butter knife than a dagger, but you still have to question the motives of smuggling it onboard. Then again, have you tried spreading cold butter on a roll at 30,000 feet (9,144 meters) with nothing but a plastic spork?

Canes are another unexpected source of deadly contraband. Every year, TSA officers confiscate dozens of "cane swords," otherwise harmless-looking walking aids that conceal full-length swords and smaller daggers [source: Burns]. Moral of the story: Never cross an old person.
