substance of bombastium. Money Bin The Money Bin is the building where Scrooge McDuck stores the portions of his money he earned by himself. Carl Barks invented the "money swim" in his story A Financial Fable (1950), followed by the "Money Bin" in the story Terror of the Beagle Boys (1951). In Barks earlier stories, interchangeably with the name Money Bin, the building's official name was the McDuck Building, which was only used on facade signs. Eventually however, the name was discontinued in the later stories by Barks and subsequent writers and artists. While the first stories showing the Bin treated it as if it had just been built, later continuity established that Scrooge had built the Money Bin in 1902 after having traveled around the world to make his fortune, mostly through prospecting and the establishment of various businesses. Scrooge's favorite pastime is to dive off a springboard into his money and swim through it. In most comic books stories, Scrooge lives at the Money Bin in his private quarters on the top floor, with the rooms often filled with large amounts of money. Because of Scrooge's frugality he has at times even made his own furniture and architecture out of his money; like using moneybags as chairs or using stacked paper bills as stairs to reach high places. The Money Bin also has a worry room in which Scrooge paces around in circles, which has caused a circular depression in the floor, to worry and ponder about hardships that has befallen him. The worry room was first mentioned in Carl Barks' story The Secret of Atlantis (Uncle Scrooge #5, 1954). The traditional location of the Money Bin is on top of Killmotor Hill which in turn lies atop a fault line which would prove catastrophic in the event of an earthquake, and this earthquake occurred in the story Land Beneath the Ground! (1956) by Carl Barks. The Money Bin is the victim of repeated assaults by Scrooge's enemies who try to steal his money, such as the Beagle Boys, who are after the bulk of Scrooge's money, and Magica DeSpell, who is after Scrooge's "Number One Dime", the first dime Scrooge ever earned. To protect against these attempted break-ins, Scrooge has installed the greatest security system in the world, which includes Gizmoduck in the DuckTales TV-Series, to thwart any thought of even trying to intrude onto the premises.
