Continuity mistake: When Max is phoning the Chief to let him know the mission's been accomplished, he takes the oars out of the oarlocks before opening his shoephone. The oars change from being out of the oarlocks in the closeups to still being in the water in the long shots for the rest of the episode. (00:23:50 - 00:24:30)
School Days - S1-E3
Continuity mistake: When Max is walking around the school grounds he walks up to man breaking a piece of wood. The man breaks a piece of wood and then bends down to pick up a new piece, leaving one on the ground. The shot changes and Max is standing there talking and the man breaks the piece of wood and bends down to pick up another one (which should be the last piece). However there is another piece left on the ground.
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.
Continuity mistake: When the owner of the shop is vaporized, at first his hands are both in front of him. The shot changes and now one arm is instantly thrown back behind him.
Continuity mistake: At the end when Max is receiving his award, he accidentally immobilises everyone in the room. The chief changes position in every shot, despite being immobilised.
Continuity mistake: When Max is attacking the boat there is a shot from inside the cabin. Watch the door. Before Max shoots, there are a series of holes in the shade covering the door (they look like bullet holes). Max begins firing and there is another shot from inside and bullet holes begin appearing in the walls. The holes in the shade however, are gone.
Audio problem: Max is firing a weapon on the garbage scow when his gun suddenly stops. He exclaims "It's jammed!", but his lips don't move. Also, what is he firing at? There's nobody there.
Visible crew/equipment: When Max and 99 have reached the mansion, they both get out of the car to look in the trunk. As they start walking, some lightning occurs. If you look up at the top, you can see where the fake sky ends and the visible back of the stage begins.
Washington 4, Indians 3 - S1-E6
Other mistake: When Max tricks the Indian's daughter, he is supposed to say, "Now close your eyes and open your mouth". Instead he says, "Close your mouth and open your eyes". The Indian woman still reacts with closed eyes and open mouth.
Continuity mistake: When Max challenges the Shark to a game of pool, Max's hand holding his cigarette jumps to the tip of his pool cue, and a chalking cube appears in his hand from nowhere. (00:19:00)
