Mr. Burns withdraws a $1000 bill from an ATM, but he drops it and an updraft carries it away to the Simpsons' house, where it is found by Bart and Milhouse.

During World War II, he made love to her the night before he was shipped out to the front lines on D-Day (having been unaware that he actually was).

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.

At the Tower of London, where he awaits his execution, he is called from outside by his family and Lisa tells him that he can use a secret tunnel that Sir Walter Raleigh built to escape.

Homer pleads with the Queen to find it in her heart to forgive him, and she allows him to leave the country on the condition that he and the rest of his family take Madonna back to America with him.

As they prepare to leave, Edwina appears and introduces Abe to her daughter Abbey, who is essentially a British female version of Homer.

[3] The plot of Homer hitting the Queen's carriage was recycled from a spec script that previous Simpsons showrunning team Al Jean and Mike Reiss had pitched to The Golden Girls.

[6] The show's staff did not know whether Blair would actually record his lines until showrunner Al Jean and his wife were in London promoting the 300th episode of The Simpsons.

[6] Blair is the only head of government to guest star in the show,[8] with Rudy Giuliani (who played himself in the episode "Stop, or My Dog Will Shoot!")

The idea was dropped after Blair agreed to guest star,[14] and it was deemed that they were not famous enough (as a married couple) in the United States and so were not approached.

[3] Tony Blair received criticism from a number of commentators for his appearance in the episode as he recorded his part at the height of the war in Iraq.

When Blair left office in 2007, it was reported that his successor as Prime Minister, Gordon Brown, was also being lined up to guest star on the show.

[23] The episode has become study material for sociology courses at University of California Berkeley, where it is used to "examine issues of the production and reception of cultural objects, in this case, a satirical cartoon show", and to figure out what it is "trying to tell audiences about aspects primarily of American society, and, to a lesser extent, about other societies".
