That '70s Show (1998)

Donna and Eric Sleepover - S2-E8

Continuity mistake: The design of Forman's Spider-Man sheets are of the Spider-Man from the late 1990's cartoon.

Halloween - S2-E5

Character mistake: At the burnt out school when they fight between themselves, Jackie says "Donna kissed Hyde last year" referring to the episode 'ski trip' in season 1 which was in the same year according to the licence plate - '77.

Moon Over Point Place (1) - S2-E26

Factual error: In one scene towards the end of the episode, Hyde is reading MAD Magazine in the Hub when Jackie interrupts him. He says he is in the middle of reading "Smokey and the Band-Aid," MAD's parody of "Smokey and the Bandit." However, the issue he has is June 1976, and the film was not released until May 1977.

Eric Gets Suspended - S2-E9

Continuity mistake: In the scene where Donna, Kelso, Eric, and Hyde are in The Hub after Eric gets suspended, Donna gets mad at the guys and leaves. But two shots later when Hyde is seen smiling and sipping his soda, you can see Donna's hair on the left side of the shot as if she was still sitting where she was before. (00:03:00)
