Found the 1990 Dirty Pair calendar on Twitter. All of the pictures reference movies. Some of them are sort of yuri-by-implication.
The OVA that the wedding dress comes from literally has Kei re-enacting the final scenes from The Graduate.
Which all has me missing the legendary Dirty Parodies by the long-defunct Pinesalad Productions. They were a work of art, with Yuri voiced as a Valley Girl with a thing for vibrators ("The fifty Radio Shack battery-of-the-month cards were my first clue." "Stay out of my drawers, Kei.") while Kei had a terrible Russian accent and an adversarial relationship with her ex-boyfriend, an agent who shows up in a few episodes ("Hey, where did you get that accent?" "Out of a book!"). Unfortunately, the Dirty Parodies never made the leap to digital (although their Robotech Parodies did) so it's possible they'll remain in the realm of legend, maybe one day to resurface in Gensokyo.
