I dunno exactly, but my brother's girlfriend's father's boss's secretary's sister's next-door neighbors' priest's cousin's union shop steward's uncle's Knights Of Columbus club Sergeant-of-Arms's nephew's best friend did it real cheap for me once.
One to petition the Ministry of Light for a bulb, 50 to establish the state production quota, 200 militia to force the factory unions to allow production of the bulb, and one to surreptitiously dial an "800" number to order an American light bulb.
