Interesting fact:

Various ghosts have been spotted within the walls of the White House over the years, but one of the most famous (and hilarious) stories comes from the English bulldog himself, Mr. Winston Churchill. Churchill was stateside on business and indulging in one of his favorite hobbies, having a lovely long bubble bath, when who should float in and disturb him but the ghost of George Washington! Churchill, the man who helped defeat Hitler, was so spooked that he insisted he be given different accommodation away from the White House.
