Buffy, in her role as guidance counselor, tells RJ (Thad Luckinbill) that "I'm not that much older than you. In fact we're practically the same age." In reality, Luckinbill is two years older than Sarah Michelle Gellar.
In the season Two's Inca Mummy Girl (1997) Devon and Oz are talking about dating. Devon asks Oz, "what does a girl have to do to impress you?" and Oz replies, "well, it involves a feather boa and the theme to A Summer Place. I can't discuss it here." The "Theme from A Summer Place" ( the music by Max Steiner for the soundtrack for the Sandra Dee / Troy Donahue movie A Summer Place (1959) ) is the music that plays each time a woman is enchanted by R. J.'s jacket.
Spike, whose aspirations as a poet date back to his human days in the 1800s, rolls his eyes after R.J.'s older brother Lance said that he'd been worried about R.J. when he discovered poetry the younger brother had written.
When talking about love spells Xander flashes back to the Season Two's Bewitched, Bothered and Bewildered (1998) where a spell goes scarily wrong and every woman in Sunnydale is lusting after him.
There are a few nods to season one's Witch (1997). In Witch, Buffy tries out for the cheerleading squad, Dawn does it here using Buffy's uniform. Dawn is also the same age as Buffy was then. RJ's magic causes Dawn to take out competition for RJ by pushing his team mate down the stairs. In Witch, Amy used magic to take out her competition for the cheerleading squad.
