Harkens back to the French bedroom farces of Georges Feydeau, the 19th century playwright, whose popular plays featured misunderstandings, slamming doors, and most of all, the pursuit of love.
After the group arrives at the ski lodge, Martin says he's going to make everyone some hot-buttered rum. Though his hands conceal the brand name on the two bottles, by the coloring they're obviously Myers's Original Dark Rum.
In this episode Niles (David Hyde Pierce) says that when he and Maris were dating, he sent her a valentine that said, "You are the girl my heart adores, Everything I have is yours." Her lawyers are now calling it a prenup. However, Niles has stated numerous times that there IS a prenup in place. (Season 4's Are You Being Served? (1997), for example).
An irony that adds another amusing layer to the romantic misunderstandings of this episode is that in real life, David Hyde Pierce (Niles) is famously gay.
