Continuity mistake: When Peter comes down to answer the phone, he's wearing a blue shirt. When he hangs up the phone, his shirt color changes to a light red/pink color. Then back to blue again.
The Séance - S1-E7
Continuity mistake: After Lucy tells Mr. Merriweather that he's invited to the seance, when it cuts to Lucy unfolding the card table legs, note the couch behind her with one normal seat cushion on the left, but in the next wideshot there's an additional shorter cushion under the normal cushion. The small towel also repositions itself neatly on the couch. (00:11:55)
Snow Falls - S1-E3
Visible crew/equipment: When the horse carriage is ambushed, just as Princess Abigail can be heard screaming "Please, help me", the camera pans downward and a horse wrangler wearing a blue baseball cap can be seen in the lower left hand corner, hiding behind one of the horses. (00:03:20)
Revealing mistake: When all the vampires are saying "for the dark", and one gets staked, there's a mark on his shirt where the stake's about to come through before it actually happens. Plus Buffy's hands are in the wrong place for her to have pushed that stake through, as well as there being no stake in her hand when the vampire gets dusted. Not only that, but the mark isn't even close to the vampire's heart to begin with. (00:34:50)
Hair By Mr. Bean of London - S1-E19
Continuity mistake: In the scene at the country fair, Mr Bean interrupts a boy doing the buzzer game. When Mr Bean is on his second go at this puzzle and stands up after unplugging the device, you can see the same boy come round a table behind Mr Bean. Cut to the next shot, the boy has disappeared from where he should be behind Mr Bean and can now be seen walking across the back of the hall.
Visible crew/equipment: At the very end of the episode, right after he tells Jesse how he used the red phosphorus to kill the gunmen, Walt leans down to vomit. You can see his microphone transmitter under his shirt. (00:54:20)
Continuity mistake: At the diner, before Mrs. Duncan comes to confess about murdering her husband, Brennan takes a sip of tea. Her glass at this point is less than half full. When Mrs. Duncan walks in, the same glass is now almost full.
Continuity mistake: Hurley's lottery ticket changes from when it is first shown to when it is shown later.
Labor Pains - S2-E8
Continuity mistake: At the beginning during the bridge jump scene, the A-Team van changes.

Visible crew/equipment: Just after the Cyber Leader orders that Flast be thrown out of the refrigerated room, one of the floor crew can be seen kneeling behind some crates. (01:20:50)
Visible crew/equipment: In the opening scene where General Clayton is explaining the 4077 to the psychiatrist, the scene changes to the outdoor set and the camera pans to the right. As the camera pans past the hospital, a white 1970s era shuttle van can be seen driving into the set in the upper right corner of the screen. (00:01:35)
Visible crew/equipment: When Jim-Bob delivers Betsy's mail she's washing her hair outside, and as she flips her wet hair back we can see the microphone under her halter top, while her arms are up. Then when she walks toward the cabin with Jim-Bob, the bulge of the mic transmitter is visible at the back of her shorts. (00:06:20)
Continuity mistake: Interior shots of Ivy's cafe show a window in the back wall of the kitchen, visible through the door to the dining area. Exterior shots of the building show only a plain stone wall where the window should be.

Continuity mistake: In the opening scene when Daphne and Eric are talking, the dish towel over Eric's shoulder is laid flat in some shots, and is twisted up in others.
Jaynestown - S1-E4
Continuity mistake: When the foreman first slaps Simon on the back, the muddy handprint has quite identifiable finger marks, but in the next shot, when Simon is walking away, the muddy shape has changed. In a subsequent shot, the mudprint has disappeared entirely. (00:04:25 - 00:06:00)
Continuity mistake: When Fry is queueing for the booth, he opens the piece of paper, showing the picture and writing. Just before he steps in to the booth, it's changed colour and gone blank, then in the next shot it's back as before. (00:07:45)
Visible crew/equipment: During the Battle of Bull Run, just before the first shell is fired towards the plantation house, at the upper part of the screen you can see a helicopter flying over the battle action. (01:45:00)
Continuity mistake: When Mike and his friend escape from the helicopters in El Salvador, Mike's hair, clothes and camera are wet just before they pass in the river. They were not wet in the previous shot. (00:04:10)
Visible crew/equipment: When Dewey yells for Lois because the bow was put on the present, if you look to the left of Lois, you will see a crewmember kneeling down, handing Lois the Red Dress, who is holding a bucket of water. He quickly gets out of the camera's view. [This is on the DVD of the first season. Someone said on the audio commentary that after catching it, they deliberately left it in to see if anyone would spot it. It's still a mistake, but that's why it's there.]
