Continuity mistake: In the scene explaining the history of the missing jade elephants, they are described as being given to ambassadors by the emperor Zhu Di of China when the Forbidden City (in China) was first opened to foreigners in 1421. When the elephants are all brought together, the representative Daichi Yoshida from the Japanese embassy comes to pick them up, describing them as "a priceless piece of our history."
Continuity mistake: During the episode when Claire and Phil do their warm-up before racing each other, their children Alex and Luke arrive from school. They get down from the car, and the car takes off and goes away. But in the 2nd shot we can see that same car parked in front of them. (00:17:00)
Continuity mistake: You can see the play director telling a pianist with grey hair to "play something modern." About twenty seconds later when Britta throws her tea hat off towards the pianist, however, it's an entirely different piano player now, that has brown/black hair. (00:17:10)
Continuity mistake: During Season 2, Episode 9 (Special Education), just as Blaine is singing "Hey soul sister, I don't wanna miss." for the last time, he is several feet in front of the other Warblers. But during the next shot, as he is singing ".a single thing you do.", he's right in front of them. So he jumped back several feet between two shots.
Continuity mistake: Tara is sitting at her desk and tells Max they will have sex the following night, and she teases him that she "Might even bring some props." Right as she says this line, the camera cuts. In the first shot, she has one pencil in each hand, but in the second shot, suddenly both pencils are in her left hand. The position of her hands changes between cuts as well.
Continuity mistake: In the car chase at the beginning of the episode, Earl Mayfield's pick up smashes into the SUV driven by Conrad Weaver. Part of the bumper comes adrift and is seen hanging low.
