The Crab with the Golden Claws: Part 2 - S1-E2
Other mistake: The newspaper article that features Tintin and Captain Haddock at the end of the episode is a flipped shot, as shown by the text that has been reversed. (00:43:35)
Doug En Vogue / Doug's Mail Order Mania - S4-E4
Continuity mistake: Doug En Vogue: While Doug is at the store, he tries to attain a new original look for himself. When he's looking at his reflection dressed as a rapper, the necklace with the word "RAP" is not a reversed image, but a moment later Doug's reflection is properly backwards as it should be. (00:07:55)
Other mistake: A time card reads 6,000,002 BC, when it should've read "60,000,002 BC". (00:07:12)
Continuity mistake: When Lemmy falls down from the window and running away from Bowser with Iggy, Iggy's face turns orange. Then later, it turns back to green.
The Losers - S1-E4
Visible crew/equipment: When Lodgepoole is telling Marshall about how the Bureau of Lost caused the Great Depression, someone's arm becomes visible in the upper left corner of the screen. (00:12:51)
Visible crew/equipment: Whilst Eddie is watching Miss World on the television, Richie walks over to the window to clear the uneaten food from the plates. In the shot shown from the window looking into the apartment, just as the shot starts, a boom mic can be seen towards the left of shot and is then quickly pulled out of frame. (00:13:55)
Visible crew/equipment: At the very end of the episode, the top of the set and crew lights are visible on the top on the screen.
Continuity mistake: While the family is eating at the table Ferguson is talking the camera is on Ferguson and Marshall. Marshall has a fork and syrup in his hands, the next shot he is now holding a cup and the syrup is near Janet.
Continuity mistake: The layout of Frank and Carol's house is inconsistent with the exterior shots. The driveway as seen from their backyard is more shallow and narrow than what is shown in the exterior shots, and the stairway to the left of their front door has a window halfway up, but the exterior shot shows a low section of roof that would completely obscure any window.
