Vint and the Kids Move In - S1-E1
Continuity mistake: When Vint moves in, he stays in the basement. Mama, Fran, and Buzz all have a "bedroom." Sonya moves into Fran's studio. Then when Naomi thinks she's pregnant, they argue over where Vint and Naomi will move to instead of the basement. Fran says she won't give up her room, Buzz says his room is in the attic. Sonya says her room is microscopic. Thelma has the biggest room. Then on Mama's Birthday, she gets Buzz to help clean out of the attic, which obviously wasn't his room as he stated. Then, of course, after Buzz, Sonya, and Fran are all gone there's only room for Thelma and Bubba upstairs.
Revealing mistake: Throughout numerous episodes while the team is supposed to be driving the van, the gear selector can be seen in the "park" position.
Factual error: Part 4: The cord on the telephone Pug uses to call Pam should be a straight wire. Instead, it's coiled: a design not yet in use in the 1940s. (00:13:30)
Continuity mistake: In the scene where Neville is telling Dennis he should find a woman, Dennis is getting dressed up in his suit to meet Dagmar. After Neville has finished talking, Dennis leaves the hut without a suitcase. But when he arrives at the hotel with Dagmar he is seen putting his case on the bed(Dagmar has one as well). It is clear that he has come straight from the hut, as he is telling Dagmar what Neville had told him before he left.
The Football Is My Best Friend - S1-E4
Continuity mistake: Roberto instructs the players to take their football everywhere. Ryo is the first to do so, but the soccer balls are in different positions from the beginning of the scene when he started the speech, even if Roberto hasn't moved. (00:02:20 - 00:03:20)
Other mistake: When Teela is at Snake Mountain, she overhears TrapJaw saying how Skeletor's electrical creature will control all of the machines at the palace. When Teela returns to He-Man, she says that the creature Skeletor created is called Byte. There's no way for Teela to know the name of the creature, since TrapJaw never referred to it by name. (00:14:24 - 00:15:20)
