* AwesomeMoments: At the end of "Chicken A La Kotter", Kotter walks out after one too many nasty comments from his boss. He and the Sweathogs take their chicken and leave...but not before Arnold goes back in and puts the head of the chicken costume on the boss's head.
* HilariousInHindsight: John Travolta would later spend [[Film/BattlefieldEarth a whole movie]] with a rubber hose up his nose.
** In one episode, Freddie gives a JiveTurkey-laden speech about how he'd run things if he were president, talking a lot about change. [[UsefulNotes/BarackObama Hmm, sound familiar?]] Also doubles as HeartwarmingInHindsight.
* HollywoodPudgy: Judy Borden. The guys call her fat and make fun of her weight, but she's only a tiny bit thicker than the rest of the girls on the show.
* VindicatedByCable: Somewhat. After its original lackluster syndication in the early 80s, the show fell into obsucrity in the US until Nick At Night and TV Land added it to their line-ups in the mid to late 90s. The episode with George Carlin was picked for Malcolm Bondon's UltimateFanHour.
