Iron Maiden
If Memory Swerves™, twas on this day in vehicular history (May 17, 1991), that UK design engineer Trevor Whitehouse patented the infamous London Wheel Clamp®. Also called the "Standing Hampton" — named after the Sharpie® rendered pudstaff and nutsack graffiti often adorning its facing — the wheel clamp was a menace to motorists but a hero to the traffic patrolling community. Few things give a properly uniformed meter maiden greater pleasure than “clamping down” on a ticket scofflaw’s deadbeat ways and Whitehouse's design proved itself one of the more ingenious crime deterrents of all time, secondary only to the electric chair, or possibly the taser gun, handgun, hand grenade, handcuff, nunchuck, night stick, cricket bat, cattle prod, switchblade knife, steak knife, slingblade, bow and arrow or iron bloody maiden. All proper instruments of weaponry and enforcement!
