Also known as "Kooky Kabuki: Part 2."
When the main cast are dressed in kabuki gear, they all wear blue kumadori, which traditionally expresses negative emotions or unsavory characters. Even Zenigata wears it, showing he's as much of a rogue as the other four.
Jigen announces himself to be a "woman-hater" ("onnagirai") in a kabuki context. "Onnagirai" is a term in kabuki used to identify men who spurn the company of women in favor of male company, a possible further reference to Jigen's suggested fluid sexuality.
This episode has one of the few times in the English dub where Jigen gives his full name.
In the English dub, Fujiko says that her breasts are aptly compared to "twin peaks". This is more or less the meaning of her name. "Mine" means "peak" in Japanese, and Fujiko's given name is derived from the mountain.
