End Game (1) - S8-E7
Revealing mistake: Boyd has a video-conversation with Linda on the phone she sent him. On top of the screen you can see how long the video will last (1 minute and 3 seconds), showing it's a pre-recorded video, not an actual live conversation.
Episode #1.7 - S1-E7
Revealing mistake: When the guitarist punches the bass player in the face you can see him miss. (00:50:02)
Heart of Ice - S1-E3

The Fight for the Final - S1-E24
Revealing mistake: Wrong perspective during the Sawada-Hyuga play makes the chasing player from Maebashi look like he's 1 foot tall. (00:18:30)

Somewhere in the World It's Christmas - S4-E15
Revealing mistake: At the end of the episode in the Peach Pit, Nat and the gang are all singing Christmas songs while Nat is playing some of the songs on a keyboard. It is very easy to tell by looking at his hands, Nat is simply miming on the keyboard.
Episode #1.4 - S1-E4
Revealing mistake: The tabloid story with the plight of the Latimers just came out, and various characters are looking at it. In the bit when David Tennant tosses on the desk his copy of the Herald, the second paragraph of the second column goes "Sitting in the family home, surrounded by pictures and mementos of Danny" etc. It is the same text that was at the very beginning of the article when the store owner was looking at it. The newspaper is a prop with the same text in a loop. (00:35:00 - 00:36:30)
Monkeyman! / Buses, Bikes and Subways - S5-E1
Revealing mistake: Mr. Simmons counts 30 students in the bus, but nowhere near that many got off (nor have nearly that many fourth graders ever been shown).
Revealing mistake: When mini is in the bath at the start of the episode you can see the bandeau she is wearing in the bath when she lays back down in the tub, probably to stop her being exposed.
Revealing mistake: At the end when Laurel and Hardy are licking Columbo, a substance is caked on Columbo's neck, presumably the food they used to get the dogs to lick Peter Falk.
With This Ring, I Thee Kill! - S1-E7

The Home Front: Part 1 - S8-E1
Revealing mistake: At the start, while John and Olivia are in the vehicle driving home, the edge of the rear projection screen is visible at both the left and right sides of the screen. (00:02:45)
Revealing mistake: When Freeth, Carter and Regan raid the flat, Freeth breaks the door down - the door starts to fall before Freeth hits it.
Row Row Row Your Boat on a Rocky Sea - S9-E1
Revealing mistake: Dr. Charles reads the patient's chart. Near the bottom, it says, "Is this enough filler? My hand hurts." (00:19:30)
The Two Deaths of Jamie B. - S2-E4
Revealing mistake: When Naomi shows Kirsten the money, you can tell it's fake. Not only are the serial numbers all the same, you can read "this note is not real it is to be used for motion pictures."
Revealing mistake: When Wan pets the cat deer for the first time, the animal pushes his head under Wan's arm. The horn then goes right through his shoulder. (00:17:55)
