Chrissy (Jade Gordon) rides a Vespa scooter covered with multiple rear-view mirrors and lights. This is a reference to the Vespa scooter covered with dozens of rear-view mirrors and lights ridden by Jimmy, an early-'70s British "Mod" (modern punk), in The Who's 1973 rock-opera album "Quadrophenia". Chrissy, like Jimmy, is on a journey to discover self-worth and identity.
At the end of the episode, after Red and Kelso successfully adjust the Pong game and Red says that Kelso has seen the future, Kelso's response is "home computers". In 2013, Ashton Kutcher, who played Kelso, would play Steve Jobs, who was a pioneer in home computers.
When Hyde has his "epiphany" upon meeting Chrissy, the international symbol for anarchy shows behind her head while the Sex Pistols' "Anarchy in the UK" plays on the soundtrack.
