The episodes "Cat Orgy," "Two Guys Naked in a Hot Tub (1999)," and "Jewbilee (1999)" all overlap in the same time frame.
Cartman is playing Wild Wild West (1999), a movie released in theaters June 30, 1999, less than a month before this episode aired and the same day as South Park: Bigger, Longer & Uncut (1999) was also released. There were several reports of teenagers and underage kids purchasing tickets for Wild Wild West and instead sneaking in to see South Park: Bigger, Longer & Uncut.
When Cartman snaps a photo of Shelly kissing Skyler he shouts "Ha ha, charade you are! Looks like you're the turd now!" This is a play on a lyric from the Pink Floyd song "Pigs (Three Different Ones)" from their 1977 album Animals.
This is the first episode to not feature all four main characters, as it is focusing on Eric Cartman exclusively. It is also the first episode where Stan and Kyle do not appear. This is the only episode of the trilogy without Kyle.
This the first appearance of Skyler and The Lords of the Underworld.
