Three Coaches & a Bobby - S3-E12
Continuity mistake: The two women near Peggy, who are sitting on the benches in the stands, are seated on the fourth and fifth levels in the wideshots, but in the close-up they're seated on the third and fourth levels.
Make Love, Not Warcraft - S10-E8
Continuity mistake: When Liane comes down after Eric says "Bathroom", you can see Cartman, and to the left, Stan. However, when the camera instantly changes to a side view, Stan is no longer there.
Other mistake: At lunch, when Sam is using a spoon to shape his mashed potatoes on the tray, his right arm clips through the tray just as he says, "Maybe I should clear out the east wall like this." Then, when Sam says, "Maybe I should fortify the south side first," he's using the spoon to move the mashed potatoes on top of the tray, but his arm and spoon are under the tray, so it looks as if the potatoes move on their own. Additionally, when Sam states that he's so confused, the spoon held up in his right hand appears to vanish in the next shot.
To Kill a Mocking Alan - S1-E5
Visible crew/equipment: When Alan drives away at the end shouting 'No way you big spastic. You're a mentalist.' the whole crew are reflected in the car windows. (00:27:10)
Visible crew/equipment: When Elliot first walks into Maya's office to find her in there with a crying Nina, a boom mic drops into view. (00:12:51)
Continuity mistake: As the stadium is shown before Thodin's walker is lowered into it, there is a panning shot showcasing the place. Then moments later from another aerial view the stadium's design is very different. Extra lights appear around the center, the layers of spectator sections doubles, and the general design of the center area changes a lot. (00:31:20 - 00:32:40)
