Sunday, Bloody Sunday - S1-E10
Corrected entry: When Kitty goes into the basement and asks for a cigarette - the sleeve of the person that hands her one is red denim, which does not match that of any of the characters there. Hyde is holding a lighter, but wearing blue denim.
Sunday, Bloody Sunday - S1-E10
Corrected entry: This episode is supposed to be October 23, 1976 but the previous episode is Thanksgiving, which is in November.
Correction: Even though it was aired as the 10th episode, the official "That 70's Show" site list this as episode 5. It was broadcast out of order, not a mistake in the show.
Correction: The sleeve is blue just like the denim sleeve that Hyde is wearing.
