-->'''Red:''' I killed people (in the Vietnam war), never said that I didn't enjoy it.

* DietEpisode: Red, after his heart attack, tries to sneak around his diet. After he gets busted, he says "This isn't food! This is what food eats!".

* IKnowKungFu: Kelso unfortunatly finds that out when he tries to beat up Jackies Co-worker after she kissed him.

* WebcomicTime: The show was on for 8 years, though in-show only 3 years passed.

* KarmaHoudini: Casey Kelso. His reputation as a charming ladies man comes off as an InformedAttribute when he's completely unlikeable who never does anything decent in any of his appearance. He acts as a corrupting influence on Donna, getting her to skip school and drink in the middle of the day -- keep in mind of course Donna is underage and much younger than him. However even when saying horrible things, he continues to charm everyone around him, which Donna even notes doesn't line up ("The words are wrong, but they sound so good coming out of his mouth"). When the parents finally intervene on his relationship with Donna, Casey just breaks it off immediately, offering no resistance to them, and walks away breaking Donna's heart. He never suffers any consequences or reprocussions. He later reappears twice, both times as sleazy as ever, and aside from a ShutUpHannibal from Eric again gets away scot-free.

** In the episode ''A New Hope'', in which the gang see the first Star Wars film, Kelso correctly guesses that Leia will end up with Han rather than Luke, a prediction that Hyde immediately shoots down.
** In the episode ''The Punk Chick'', Kelso and Red modify a [[Pong Pong]] game system to make the paddles smaller, thinking the game is too easy. Upon successfully modifying the system, Kelso excitedly predicts that "home computers'' are the future. Red dismisses this as nothing more than Kelso being his usual [[CloudCuckooLander Cloud Cuckoo Lander]] self.

* CloudCuckooLander: Lots of characters have moments of this (especially when they're in the circle), but Fez and Kelso have the most.

* {{Bishonen}}: Kelso is better described as "pretty" than "handsome." [[LampshadeHanging Lampshaded]] by Kelso himself:
-->'''Kelso:''' I'm what's known as "man-pretty."

* SuddenlyEthnicity: Hyde and his real family.

* TheScrappy: Randy, Eric and Kelso's ReplacementScrappy, is hated by most fans.
** Laurie is an intentional example.

** JerkassSue[=/=]KarmaHoudini: Kelso's older brother Casey, who does not do a single decent thing in any of his appearances, yet has every female drooling over him. In his relationship with Donna (who is underage), he seduces her, checks her out of school on a regular basis, and gets her drunk in the middle of the day. When this last act finally gets the parents to take notice of what he's doing to her, Donna prepares to fight for their relationship, but Casey submits instantly, breaking her heart and walking away with no retribution.
