On an indecently cold winter morning, I was waiting for my bus to go to work, shivering and trying to pretend I didn't want to run back home and stay inside until spring.  I was listening to "Nine Inch Nails", and I turned it up louder to fight the cold.  Trent Reznor's voice sang, "Memorabilia, memorabilia....", and my mummy biased mind warped it into "mummerabilia".
