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. Marge makes Bart and Homer put up fliers so that the person who lost the bill can reclaim it. No one can describe it correctly so Lisa suggests that they spend the money on something for Marge. Marge desires a dream vacation, but decides against this because Homer always manages to ruin any trip they go on. After realizing he can make money from the bill, Bart displays it in a museum in his tree house. Mr. Burns visits and reclaims his money, forcing Bart to close his museum. However, Bart has made over $3000 from the museum so he reconsiders Lisa's suggestion and decides to spend the money on a vacation for Marge. Grampa suggests they go to Britain, where he hopes to meet his long-lost love Edwina. During World War II, he made love to her the night before he was shipped out to the front lines on D-Day.
