But THIS is a Sears "Die Hard" Dummy Battery... and is meant for "Die Hard Dummies" :>)
"Welcome to Nakatomi Plaza... Mr. McClain... Would you like a Complimentary Die Hard Dummy Battery sent up to your Room... Sir? They Don't hold much of a Charge, but... If you drop it down an Empty Elevator Shaft from the 31st Floor on top of Hans Gruber's Crew... It CAN leave One Hell of an Impression on the Minds of those Dummy Terrorists... Sir." :>)
