Home Alone 4 - S1-E3
Visible crew/equipment: When the boys come out of the front door of the house to load into the van to go to the hospital the camera crew reflection is seen on the large picture window beside the front door.
Continuity mistake: When the boys are wrapping their parents present, Dewey is holding a bow in some shots and not holding one in other shots.
Revealing mistake: At the end, Malcolm speaks to camera with several children moving in the background. One boy doesn't know where or when to move and he tries to speak to someone off camera. In the end he gives up, shrugs his shoulders and walks off.
Other mistake: Reese is playing a Game Boy without a game in the slot.
Continuity mistake: When Lois is packing lunch in the blue cooler her hands go from on the side of the cooler to down by her waist in one frame to the next. No time for her to move it.
The Bots and the Bees - S1-E14

Continuity mistake: When we see Dewey's friend at the table eating cereal he is eating cereal and the bowl is full of milk. In the next shot the bowl is full of cereal and there is barely any milk.
Continuity mistake: Hal speaks about having held Malcolm the moment he was born. But in the Season 2 episode "Flashback" not only was he not there for his birth, he didn't hold him immediately, instead he talked to Lois.
Continuity mistake: During the scene when Lois says that Malcolm is a genius, his arms keep changing position between shots.
Visible crew/equipment: You can see the crew right after the intro. (00:01:00)
Continuity mistake: When Malcolm goes into the classroom and gives his teacher a hamburger she eats about half of the burger really quickly but in the next shot of the hamburger there appear to be only a few bites taken.
