Homer and Marge spice up their love life by risking ''very'' indecent exposure in public places. Meanwhile, Bart and Lisa play around with a metal detector and finds a film reel containing the lost ending to the 1942 classic ''Film/{{Casablanca}}''.

!! Tropes:
* BaitAndSwitch: When Sideshow Mel sees Homer at the football game.
-->'''Sideshow Mel:''' Look at that blimp! He's hanging from a balloon!
* {{Balloonacy}}: The naked hot air balloon sequence
* BritishStuffiness: The maid who gets startled at Homer's shirtlessness has a decidedly British accent.
* ComicallyMissingThePoint: Bart believing his parents would be disappointed once they realized they forgot them after Homer and Marge get so aroused that they drive off to the mini-golf course.
* EverybodyDies: According to the Crazy Old Jewish Man, the lost ending to ''Film/ItsAWonderfulLife'' was originally going to end with a killing spree.
* GettingCrapPastTheRadar: "If there's anyone in there, you're in for a serious ass-forkin'!" [[WordOfGod According to the DVD commentary]], Matt Groening really hated that line, despite the other writers finding it funny.
** A lot of the nudity counts too, as it really tested how far FOX would allow animated nudity on the channel. See HotterAndSexier below.
* HotterAndSexier: For better or worse, this episode pushed the boundaries of sexual content and animated nudity for primetime TV. Because of this, the UK and Australia have given this episode higher ratings than usual (in the UK, this got a 12 rating [though it's a PG on the DVD] and this episode became the first episode in Australia to have an M rating [the "M" rating is the highest free-TV content rating your show can have, like America's TV-14 rating]). In America, this episode was rated TV-PG for sexually suggestive dialogue (D), sexual content[[note]]including nudity and scenes of implied intercourse[[/note]] (S), foul language (L), and violence (V).
* LamePunReaction: Homer and Marge's attitude to the restaurant the kids take them to for their anniversary - Up Up and Buffet! (a plane restaurant)
%%* NakedPeopleAreFunny.
* {{Retirony}}: Chief Wiggum's police dog had only one day until retirement when it was scared off smelling Homer's underwear.
* RollInTheHay: Homer and Marge make love in a hay barrack on a farm.
* SceneryCensor: Homer and Marge's naughty parts get covered up by a pair of lawn ornaments after they escape the golf course. Homer asks if they can switch because he didn't trust his (two gnomes sawing a log).
* SequelHook: The lost ending to ''Casablanca''.
* SlipknotPonytail: Marge's hair coming down in the rain is clearly meant to evoke this.
* TemptingFate: After naked Homer and Marge land in the football stadium, shocking everybody, Homer sarcastically asks "Why don't you take a picture? It'll last longer!" Unfortunately, everybody does, since it happened to be Camera Day.
* UnusualEuphemism: "Rock the Casbah" for having sex.
** And the song itself is played over the end credits.
