It is
Homer and
Marge's eleventh
wedding anniversary and
Grampa does not arrive at the Simpson house to babysit the children having mistaken them for the Flanders children next door, spoiling Homer and Marge's evening together. Later that evening, Homer and Marge attempt to have
sexual intercourse, but lack
enthusiasm. The following day, the refrigerator's motor burns out after Homer left the door open to look at a slice of his and Marge's wedding cake. As Homer and Marge make their way to a hardware store to buy another one, their car gets stuck in the muddy driveway in the middle of farm country. Homer and Marge rush into the nearest barn to avoid a sudden storm. A farmer discovers the barn door is open and suspects trespassers. He enters the barn, nearly catching Homer and Marge, who are hiding in the hay loft, but leaves after failing to locate them. When the coast is clear, Homer and Marge have inspired sex in the hay loft. Homer and Marge think their marriage has been recharged and go for a romantic weekend at a
bed and breakfast, but soon fall into their old patterns. However, a maid walks in on them and they conclude they are both
aroused when they risk being caught during intimate moments, so they have sex behind window curtains in a room full of people. Their love life is recharged and one day they begin to have sex on the same miniature golf course windmill where
Bart was
conceived. This time they come
too close to being caught having
public sex, and while they manage to escape, they have to flee through
Springfield naked. After trying to seek help from
Gil at his car lot, they steal his hot air balloon and fly throughout the city in it. As Marge tries to pilot the balloon after Homer falls and is left hanging on the rope, the balloon lands in a
football stadium, and a naked photograph of Homer and Marge appears in the local newspaper. The next day, Bart and
Lisa see the picture and their parents begin to explain sex to them. Before they go into detail, however, they decide to go back to the miniature golf course. In a subplot, Bart and Lisa stay at the Springfield Retirement Castle with Grampa, and they discover a
metal detector in his closet. While Bart uses it to look for pirate treasure, they uncover a
film reel of an
alternate ending to
Casablanca. They watch the scene, which turns out to be a very sanitized and typical Hollywood happy ending, where
Humphrey Bogart and
Ingrid Bergman's characters marry in the end. Bart, Lisa and Grampa all like it but the
Old Jewish Man reveals that he was once a
studio executive and tried to include this happy ending on the film. Disgruntled, he pays Bart and Lisa to dispose of the reel, along with another reel of a killing spree ending to ''
It's A Wonderful Life''. ==Production==
