Upon their arrival in London the family is greeted by the Prime Minister, Tony Blair, whom Homer mistakes for Mr. Bean. They visit London's tourist attractions, and later meet J. K. Rowling and Ian McKellen. Grampa tries to contact Edwina whilst Bart and Lisa go on a "sugar rush" after discovering the joys of British candy. Homer and Marge rent a Mini Cooper and start to drive around London but get stuck on the roundabout at Hyde Park Corner. After literally driving in circles for hours, Homer decides to break out of it, plows straight through the gates of Buckingham Palace and slams into Queen Elizabeth II's horse-drawn carriage, and is beaten by the Foot Guards.
