Presidents William Henry Harrison and Zachary Taylor both died in the White House. Three First Ladies—Letitia Tyler, Caroline Harrison, and Ellen Wilson—passed away there, too. To date, a total of 10 people have died within the White House walls. If that made your ears perk up, check out The Weirdest Urban Legend in Every State.

Nobody likes moving day, but you can bet yours is nowhere near as stressful as moving day at the White House. It all takes place as soon as the sitting president leaves the White House for the president-elect's inauguration ceremony. From then, staffers and movers have five hours to move out all of the sitting president's belongings and move in the belongings of the president-elect. Not only is furniture changed and artwork swapped, but the walls are even repainted too, as per the requests of the incoming first family. All in five hours!
