Winter Luau - S1-E9
Other mistake: When Lucas is about to take Alexa from her friends, you can hear them re-using an audio clip from a previous episode, "But if I tell them the same thing is gonna happen to me" which would only apply if this was before Alexa tells everyone that she is the one with cancer.
Other mistake: At the very beginning of the episode, Fletcher wakes up in bed and his hair is perfectly combed.
Other mistake: It is daylight outside when Cliff and Clair are talking, but when he turns the lights off to try on his light-up Father's Day gifts, it gets pitch black in the room.
Other mistake: Right after Sam tells Carla he will sleep with the next woman who walks through the door, in the background there is an "Extra" (blonde-haired woman seen in the background behind Carla) who starts to cross right then turns and crosses left then turns right and stops and looks confused as to where she is to cross. Obviously she was given directions of which way to cross and when, but forgot. (00:04:15)
Other mistake: When the kids are opening their lockers, they enter the code, then pull on the lock to open the locker. The closed lock is still attached to the front of the locker. When they close it, it's magically locked again without them ever opening or closing the lock. In reality, these locks would be useless, or the locker doors wouldn't open.
Other mistake: Tails automatically knows Cosmo's name even before she introduces herself later on (English Dub version only).
Other mistake: When the opening credits are shown, the door to the basement is in the kitchen. In the beginning of the series the door is still in the kitchen, but in later seasons the basement door is in the laundry room, but in the opening credits it is still in the kitchen.
Suggested correction: I had noticed the same thing and thought it was a continuity mistake. However, in Season 3, Dan mentioned building the back service porch where Roseanne does the laundry. There are two basement accesses, the one in the kitchen, and what was probably the outside entrance in the backyard that is now enclosed inside the service porch. The family prefers using that one. Most houses, mine own included, have multiple basement access, one inside the house and one outside. In my state, it's a building code requirement.
Other mistake: The bridge jump scene in this episode is recycled from the season two episode "Labor Pains" where the van changes.
Other mistake: The bishop that Dougal talks to about religion being pointless is supposed to be Irish but when he is telling Ted about his change of heart, the actor's English accent slips back in for a few seconds.
Other mistake: In the end of the title sequence, Jessie walks outside. Before exiting, you can see that she is just a little bit taller than the doorway, but her head passes through the frame as she walks forwards.
Other mistake: When the phone pole was installed with a "butt set" to talk with, they used it upside down for a long time. Someone must have brought it to the director, because they finally corrected the problem.
Ring Finger - S1-E10
Other mistake: When Jackie uses the hammer to smash her Ring Finger, if you watch carefully the prop hammer actually hits her middle finger instead. (00:24:30)
Other mistake: The score board says Huskies 16, Visitors 14, with 16 seconds left on the football game. But the story is that Eve, who is the kicker for the Huskies, kicks the winning field goal. The Huskies are already winning. (00:10:00)
Other mistake: A time card reads 6,000,002 BC, when it should've read "60,000,002 BC". (00:07:12)
The Strange Fate of Conrad Meyer Zulick - S3-E9
Other mistake: When Doc Donovan reads the wanted posters, the physical description of Heyes mentions dark brown hair and brown eyes, which fits Pete Duel. However, by this episode, Roger Davis had taken over the role. He has light brown hair and blue eyes.
Other mistake: Captain Eureka losing his finger makes absolutely no sense. He doesn't cry out in pain, there's no blood, and where the finger ended up is completely illogical. The finger didn't just sever on its own; it's shown that severing only occurs when passing through objects. Captain Eureka goes through a wall that is a good fifteen feet away from where the finger is discovered, and it is implausible to think it could have rolled there on its own.
Other mistake: During the hold up when Medhurst is sprung from the police van, the breakdown truck used to pull the doors of the van reverses towards the police van twice after releasing the chains off the doors before driving away, and the camera lights are reflected in the side of the white getaway car.
Don't Fool With a Phantom - S2-E8
Other mistake: When the wax phantom appears behind Scooby and Shaggy the man who supposedly is impersonating him in the suit is in clear sight directly behind Fred Daphne and Velma.
Other mistake: In episode 3 Jimmy says to Kim that the Kettlemans bought a boat using some of the money they embezzled. Nevertheless, when Mike breaks into the Kettleman's house and gets the money back which later is delivered to the district attorney in this episode, it's the whole amount without any money missing.
