School Days - S1-E3
Revealing mistake: When Max is being attacked with throwing knives, one is thrown into the closet door. Watch closely; the wire used to guide the knife is visible.
Revealing mistake: When Hymie is investigating the unconscious man in the shower, for some the reason the man is wearing underpants even though he is in a shower. Evidently for modesty.
Revealing mistake: When Purvis is about to go onto the field, it cuts to a close up of Purvis' face and you can actually see folds in the fake sky behind Purvis.
The Wax Max - S3-E20
Revealing mistake: In the tunnel of Love scene, one shot shows an axe being thrust down at Max. The axe is visibly blunt.
Viva Smart - S3-E2
Revealing mistake: The drawers in Max's hotel room have no bottom part in them, but Max passes right between the two drawers when he straightens up, so they have no inside-facing part either.
Viva Smart - S3-E2
Revealing mistake: The juggler accidentally drops the ball in his act, but if you look at the final part of his performance, he deliberately holds one of the balls in his hands so he can miss the final one.
The Spy Who Met Himself - S3-E1
Revealing mistake: When the fake Chief calls Max over to the car, the driver is meant to be a double of Smart, but the driver is not Don Adams.
The Spy Who Met Himself - S3-E1
Revealing mistake: When Max is thrown in the dungeon, the man being dragged down the steps is not Don Adams.
The Spy Who Met Himself - S3-E1
Revealing mistake: In a few shots of the dungeon scene, both Maxes are shown. The one with his back to the camera has a different-shaped head to Don Adams, revealing him as a double.
The Spy Who Met Himself - S3-E1
Revealing mistake: Siegfried shoots his two thugs, but neither one has a bullet hole in their jackets when they get shot.
Revealing mistake: Any time a laser is fired in the show, there are no scorch marks on the walls where they hit.
Revealing mistake: When Hymie does the high jump, when the film cuts to a shot of him clearing the bar, Hymie's hair is curly when it should be flattened down like when he took of and as he landed. It is obviously a stunt double.
To Sire, with Love: Part 2 - S4-E21
Revealing mistake: When the tarantula is released into the room, the spider is a plastic model in its container when it's on Max's shoulder, and when they kill it with the horseradish.
Revealing mistake: When Max and the other control Agents are old, you can see the powder on their faces used to make them look old.
Revealing mistake: When Max and 99 are rowing away on the Chief's inflated diving suit, you can see that the Chief is not in the suit and it is just an inflatable raft.
Revealing mistake: Siegfried uses the magnet to push the ship away from the island. However, you can see the scene is reversed; the steam from the ship is going back into the funnel.
Revealing mistake: When Max accidentally shoots the life raft with the flare gun, he visibly doesn't make a hole in the raft. It's likely it's ink or ash or another black material to look like the raft had a hole burned through it.
Revealing mistake: When Max crashes through the wall in the prologue, you can easily tell it's a stunt double. You don't even need freeze frame to see it, as the screen freezes, stylistically fades, then the title sequence starts.
Revealing mistake: At the start, when Max falls off his police motor cycle, he is obviously a stunt double.
Revealing mistake: When the Prime Minister's aide falls out of the car, he is a dummy.
