Tanks For The Memories - S5-E15
Continuity mistake: The boys had different haircuts in the previous episode. Randy had just gotten a haircut, and in this episode, the kids are younger and have their longer hair right back. (00:05:50)
Deliberate mistake: Lily was an infant for all of season 5, but beginning with this season, she is around 5 years old. The show didn't jump forward in time, because JT states in a season 5 episode that he is 19, and in the episode this season where he and Rich go to Mexico, he states that he is almost 20, as well as Al and Mark are both still in high school.
Continuity mistake: When Ritchie, Eddie, Spudgun and Dave Hedgehog enter the pub with the fake money and order drinks, Ritchie asks for Absinthe but is told that the pub doesn't have any and is given Pernod instead. Later, when the £5000 pub quiz poster is pointed out, Ritchie says he's had half a pint of Absinthe and can't see anything. Where did the Absinthe come from if the pub didn't have any earlier in the episode and they never left?
Doug Takes a Hike / Doug Rocks - S1-E4
Continuity mistake: When Roger is dancing in Skeeter's yard, he changes color.
Revealing mistake: In the parking lot shot, one patron of the Leisure Center warns an arriving patron that Brittas is back, prompting the arriving person to reverse their car out of the parking space. However, note the arriving patron's hands - his car was already in reverse before he was spoken to. (00:12:15)
Other mistake: A time card reads 6,000,002 BC, when it should've read "60,000,002 BC". (00:07:12)
Relax-Ay-Voo - S4-E7
Visible crew/equipment: When Bill and Rona are talking in the kitchen the shadow of the mike can be seen on Bill's brown jumper.
Continuity mistake: Tony Sparkle is seen defacing a picture of Judy Talent. He starts writing something beginning with T. The action cuts away for a moment, and then back again. The words on the picture are "SAD OLD BAT". (00:07:05)
Continuity mistake: When Janet gets off the phone with Clarissa's principal, Clarissa is standing on the right side of her friend. The shot changes and she is now on the left.
Bug Off/The Crawl Space - S9-E5
Continuity mistake: In Moving Away, Tommy tells the other Rugrats how they first met when Angelica lied about the nasty things they did. However in the Crawl Space, there is a flashback of Tommy, Chuckie, Phil and Lil playing in the playpen when they were younger. Chuckie is scared of the Jack-in-a-box in that flashback, so the Rugrats could not have met for the first time back then.
A Breath of French Air (2) - S1-E6
Character mistake: It is mentioned several times that the Larkins' holiday to France takes place in August. Whilst on the beach, Ma Larkin says that Mariette and Charlie's first wedding anniversary is the following week. However, it is established in the previous two part episode, 'When the Green Woods Laugh', that their wedding date is the seventh of July, the same date that Pop has to appear in court.
Audio problem: The director can be heard saying "Action" at the start of the scene. (00:16:35)
Revealing mistake: When the holder of the nude seminar's handing papers to Louise, you can see that behind the lectern she's wearing underwear. (00:14:00)
Continuity mistake: When Marshall first finds Trip's letter, he holds it from the left side. In the close-up, he's holding it from the right side. (00:02:10)
Continuity mistake: At the start of the baseball game Kevin is holding a baseball bat. The end he is holding the bat changes between shots.
