Best Known for the Fanservice: Quick, what's the first thing you remember from this movie? Judge Reinhold getting fired from his job? The gas station robbery scene? Bullshit. You remember Phoebe Cates removing her top. Don't even try to deny it.
The story goes that video stores' copies of the VHS tape broke from having that scene re-wound and played over and over and over again.
Thanks to this film, there is an entire generation of men who can't hear "Moving in Stereo" by The Cars without thinking of Phoebe Cates' boobs.
Just Here for Godzilla: The Phoebe Cates topless scene is so famous that some people have admitted to renting, buying, or illegally downloading the movie just so they could see it. In addition, many video store owners have claimed that quite some copies of the film in their stores have tracking errors when the scene is featured, due to customers constantly playing and rewinding the scene over and over again.
The scene where Phoebe Cates climbs out of the pool and removes her top has been parodied countless times over the decades, with spoofs of the scene appearing in The Man Show, Family Guy, and even the video for "Stacy's Mom" by Fountains of Wayne.
While nowhere near as famous, the scene of Spicoli on the phone with his friend, repeatedly whacking himself on the head with his shoe to prove how stoned he is, is also quite popular.
Signature Scene: Linda coming out of the pool and removing her top to kiss Brad in his sexual fantasy.
Values Dissonance: There are several instances of passive homophobia, such as one student taping a note that reads "I'm a homo" to another student's back and Spicoli's exclamation of "Those guys are fags!", all stuff that's sadly not uncommon in high school settings. Considering how much more seriously the emotionally damaging consequences of this type of bullying are now taken, none of these jokes would pass nowadays.
Vindicated by History: Upon release, the movie was largely panned by critics (no doubt due to the already-existing glut of high-school/college sex comedies during that era). Today, it's considered by many to be among the best high school movies ever made.
Made double by the fact that many of the film's vindicators are critics who had actually formerly bashed the film when it was released, admitting that they let their emotions cloud their judgments.
