Plot
It is Homer and Marge's eleventh wedding anniversary and Grampa does not arrive at the Simpsons house to babysit the children. As a result, they decide take Bart, Lisa and Maggie to a fancy restaurant with them.

Homer and Marge make their way to a hardware store to buy another motor, but the car gets stuck in the muddy driveway in the middle of farm country. Meanwhile, Bart and Lisa stay at the Springfield Retirement Castle with Grampa, and they discover a metal detector in his closet. Using the detector, they use they uncover a suppressed, happy ending to the film Casablanca in which Ilsa Lund and Rick marry. The Old Jewish Man steps forward to reveal that in his younger days, he was a studio executive that had tacked that happy ending onto the picture. He then gives Bart and Lisa twenty dollars to re-bury it, along with another film reel labeled, "It's a Wonderful Life: Killing Spree Ending".

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 sexual intercourse in the hay loft. They 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.

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, and while they manage to escape, they have to flee through Springfield in the nude. In the end, the two are seen in an football stadium, and a naked photograph of Homer and Marge appears in the local newspaper.

Production
"Natural Born Kissers" was the first episode written by Matt Selman, who partly based it on his parent's marriage. The episode was the only time that Mike Scully ever got a call from Fox where they suggested not doing the episode. They were worried about the sexual content, the nudity and how it was going to be handled. It was the first episode to ever receive an M (15+) rating in Australia. They disliked several of the phrases used in the episode, such as the term "ass forkin'". In an interview, Matt Groening said "The network censors couldn't believe it, and neither could I: the cow at the peephole while Homer and Marge make love in a hayloft; neighbors groping Homer when he and Marge are caught nude inside the windmill at the Sir Putts-A-Lot mini golf course; Homer dangling naked from a hot-air balloon, his ass dragging against the glass of a Crystal Cathedral-like church." The producers fought the censors and in the end, very little of the script was changed. Marge's behind is also shown on television for the first time. Marge and Homer in the golf course is a reference to the season 3 episode "I Married Marge", although in that episode they are in a castle, rather than a windmill.

The idea for the episodes couch gag came from Dan Castellaneta's niece, who was given a special credit for it.
