Hohenheim: Thanks to the magic of fanfiction, this van will fit us all.
Selleck Waterfall Sandwich is a fifteen-chapter musical parody of Flower Drum Song by Oxenstierna D. Yuki-Rin. In the fic, Kagura and her brother, Kamui, arrive back to Earth after a vacation on their home planet so Kagura can marry Sanji, who is already in love with Nico Robin. When Kamui discovers this affair, he sets his sister up with Hayato Gokudera, who becomes fast friends with Kagura. Unfortunately, Robin's mother, Nico Olvia, does not approve of their friendship. Things go downhill when Olvia takes a restraining order out on Gokudera and Kamui decides to abuse loopholes by possibly marrying Kagura with Okita. Hilarity Ensues.
This fanfic was first published in November, 2010, shortly after Oxenstierna D. Yuki-Rin got her account. She posted the final chapter in December of that year.
Selleck Watertrope Sandwich:

- Anti-Love Song: Gokudera sings "There's a Fine, Fine Line" in chapter three.

- Artistic License – Biology: Played straight with this exchange in chapter three.Gokudera: "Nico Olvia is feminine? I don't think so. Did you see her rock the mom jeans? Plus, how does a silver-haired woman give birth to a black-haired woman?"Kagura: "Did you even learn about genetics in Biology class?"Gokudera: "I never paid attention to it, because it was a really boring chapter. I think I also bombed the test on that material."
- Bad Girl Song: Robin's bad girl song is I Like it Rough. When she sang it in chapter 12, Gokudera's plans to break up Sanji and Robin fail right in front of his eyes.
- Big Eater: Kagura and Bonney. Subverted in chapter three when they are in an eating contest against each other.
- Bilingual Bonus: Chapter nine's title is, "iSimon!", which is Spanish for, "Hell yeah!"
- Boyfriend Bluff: Kagura does this with Yamamoto for a short time so they can abuse loopholes with Olvia's restraining order.

- Did You Just Have Sex?: Kamui, Gintoki, Kagura, Tae, and Shinpachi have this moment at the end of chapter one when they (think) they see Sanji and Robin getting it on. Kamui has the same moment in chapter two with, unsurprisingly, Sanji and Robin.
