Some fun 'retro' elements to this episode - when Chyna time-travels back to 1986 with Zoltan-as-teen, and he asks "come with me to the prom", she worries aloud "but what will I wear?". He suggests "how about what you've got on?", and Chyna retorts "can't do that -- in my time this outfit is Seventies-retro. But in the Eighties, this is just out of date."
At the prom itself, she marvels "it's the Eighties! Wow, the Eighties are so.... Eighties"
This is proved by a 1986-girl's Valley-Girl-ing it with "totally" after "totally" after "totally", and the prom band, whose members play keytars!
Chyna sings with the band and when they struck up a song, she exclaim, "really, this song?!!?! My mom listens to this song on Oldies 107", then blurts hastily, "I mean, Newies 107".
