==Trivia==
*Homer is shown shaving off his stubble, which grows back moments later. This gag was also done in "Some Enchanted Evening", where Homer has a clean shaven look for precisely seven seconds, then his stubble regrows.

**Weight Loss Through Laborious Sex
**Bordello Repair Volume I
**Bork on Sex
**How to Seduce Your Lousy, Lazy Husband
**Kama Sutra (which Homer looks at)
**Kosher Erotic Cakes
*Among the rooms at the "Aphrodite Inn Fantasy Rooms and Conference Center" are the following:

**The Caveman Room (Mayor Quimby, dressed in an "appropriate" outfit, comes out to say that the toilet is overflowing.)
**The Safari Room
**The Camelot Room
**The Utility Room (the hotel's actual utility room; Homer and Marge end up here because everything else is booked.)
*Originally, the subplot relating to the kids was supposed to end with their learning from Ralph Wiggum what was actually going on. However, it was cut from the episode when it aired because the writers couldn't figure out how to justify someone like Ralph as having any knowledge about sex.
*The opening scene where Bart interrupted Marge and Homer's amorous moment was originally going to be more explicit, showing Marge and Homer's bodies in full as they're panicking. This version was later used for the "Hardcore Nudity" montage of "The Simpsons 138th Episode Spectacular".

*When Abe initially advertises his tonic to the crowd, the part of Abe's beard behind his glasses repeatedly is colored yellow like his skin.

*In this episode, both Homer and Grampa set fire to the Simpson farm, and it burns to the ground. The later episode "E-I-E-I-D'oh" creates a plot hole, as the Simpsons temporarily move to the Simpson farm, though it could have been rebuilt.
*In one scene in Bart's treehouse, Wendell's skin is yellow, rather than its usual white color.
*After Barney falls over, his belly turns the same color as his shirt.
