Mr. Burns uses his ATM card and gets a $1000 bill. It hits him in the chest and then blows away, right across town and into the Simpson living room window, where Bart gets a hold of it. His parents (well Marge anyway) make him put up a notice so that the owner might have a chance to claim the bill. When no one can identify the bill, Bart wonders what he can do with his new windfall. He realizes that he can make money showing off his bill, so he opens up the "Museum of Modern Bart" in his tree house. Mr. Burns makes his claim for the bill, but all is not lost. Bart has made over $3000 in admissions to his museum. To make use of the money the family decides to go to England, where Abe recalls having a memorable night with a beautiful English girl named Edwina. In merry ole England, the Simpsons meet Prime Minister Tony Blair. Abe tries to find Edwina, meanwhile the rest of the family tours London. Everything is going fine until Homer slams his rental Mini into the back of the Queen's horse drawn carriage. Homer is put on trial, makes an ass out of himself in court and is thrown into the Tower of London. Lisa finds a way for Homer to escape his tower cell, a secret tunnel once used by Sir Walter Raleigh. Unfortunately the tunnel leads to the Queen's bedroom. Homer's pathetic plea with the Queen works and the family is allowed to leave the country, provided they take Madonna with them. Before boarding the plane, Edwina calls out to Abe, and introduces him to her daughter of 58 years, Abbie, a woman who looks like Homer in drag. Abe runs on board the plane as fast as he can.
