These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Crowning Music of Awesome: The famous soundtrack, which, for at least 10 years after the film's release, was not available in wide release until Rhino Records released not just one, but two soundtrack CDs.
Modern English's "I Melt With You" plays during the montage of Julie's dates with Randy, as well as when they escape the Valley High junior prom, heading to the Valley Sheraton in Tommy's rented limousine.
Stalking Is Love: Though Randy is the penultimate example of this trope, the scene where Skip decides to go to Suzi's house to see if Beth is home could qualify; under normal circumstances, if no one answered the door someplace that someone was visiting, that someone would leave. Skip, however, not only does not go away, but actually enters the house (either he is an expert lockpicker, or he found a hidden key) and tries to ascertain if Beth is home. Though he knows that what he is doing is crazy, he still goes upstairs to look for Beth and seemingly finds her taking a shower. Subverted when Skip is apparently having sex with Beth when Suzi comes home and goes upstairs, but the way the scene is presented shows that when the bedroom door opens, Beth was the one who had been out and has come home, and Suzi had been in the shower and is caught in bed with Skip.
The subversion seems to indicate that either Skip is a horndog who decided to "settle" for Suzi since Beth wasn't home, or that he discovered that he liked Suzi after all. It's never said either way, but the fact that Skip and Suzi go to the prom together and Loryn figuring out that they had gotten together seems to indicate the latter.
