I think we'll go with the Tenchi one.
He's with Sailor Moon. Things don't go so well at first. First, while at a coffee shop, they bump into Goku, who wants some more hentai action. He fights Tenchi. Tenchi is losing, & Ryoko shows up. Ryoko throws a cup of coffee at Gofu, which excites him. (Now, Ryoko & Goku are starring in hentai films).
After that is over, they go to the theater, where Tuxedo Mask is working as an usher. Seeing Sailor Moon, he makes up a lie about the planet at risk of being attacked by aliens. Sailor Moon believes him, & convinces Tenchi to help. In space, Tuxedo Mask reveals the truth & tries to finish off Tenchi. Sailor Moon notices that almost all of their clothing has been destroyed, so she whips out a Yaoi paddle & smacks Tuxedo Mask into the Sun.
Tenchi has no given up on romance & has become a munk.
