Advanced Introduction to Finality - S4-E13
Continuity mistake: In episode 11 of Season 4, it was stated that Leonard got an A in 1968, then opted for pass/fail to have the highest GPA in the college. In the final scene of this episode, however, it shows Greendale college as being established in 1974.
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)
Introduction to Finality - S3-E22
Other mistake: During Leonard's "Let's Potato Chips" YouTube video during the ending credits, you can see the video reaches the end of the load/play bar (watch the circle), yet the video continues for several seconds. Once the circle reaches the end of the load/play bar, the video is over and won't continue.
Continuity mistake: During the scenes in the pool area and the locker room, posters can be seen in the background with the Greendale Human Being on them. However, the Human Being mascot isn't invented until the next episode.
Custody Law and Eastern European Diplomacy - S2-E18
Character mistake: Annie when giving her gifts is holding two little mini flags to cover the possible ethnicity of Shirley's baby. One is a Chinese flag and the other is Zimbabwe. Annie makes reference to the fact that the ethnic food she made is one from Ghana. She makes Ghana ethnic food but does not get the right flag for Ghana. She decorates the table with numerous flags which are also Zimbabwe.
Contemporary American Poultry - S1-E21
Continuity mistake: An adhesive sign reading "Respect the Noble Animal" and a "Danger" sign behind Jeff disappear after the next reverse-shot. (00:11:54)
The Psychology of Letting Go - S2-E3
Continuity mistake: When Professor Duncan comes into the classroom, he circles and underlines "anthropology." When Chang walks in, the circle and underline change drastically. It goes back to the original way in various shots.
Accounting for Lawyers - S2-E2
Character mistake: At the party, Jeff is talking to Ted about his parents' divorce, which included a custody hearing. Jeff mentions the divorce lawyer drove a Mercedes SLK. However, the SLK didn't come out until 1996, which would make Jeff at least 21 (turning 22) at the time of the divorce (he was born Nov 1974). There would have been no need for a custody hearing (Jeff was an only child between his mom and dad) and his parents divorced when he was very young, so the divorce had to happen prior to 1996.
Aerodynamics of Gender - S2-E7
Visible crew/equipment: When Pierce's drone is following Jeff and Troy, as the two go through the bushes, you can see the string the drone is attached to as it "hovers."
Mixology Certification - S2-E10
Continuity mistake: Near the end, when Jeff says to Troy "you're a man now" the camera goes onto Troy and we can see Abed asleep on Britta's shoulder (Britta is also asleep), even though in the shot before that, they were both awake. Then after the shot of Troy we see Britta and Abed awake again.
Advanced Documentary Filmmaking - S4-E6
Continuity mistake: Abed is making a documentary, and we see the fact that there are two cameras throughout the episode, so they are definitely acknowledged. However, in the scene at the trout fisherman's house, there is someone filming behind Annie and Troy and towards Annie and Troy. The problem being that whenever it shows Annie and Troy in front, there is no cameraman behind them, but when it cuts to behind them again there is somebody there filming.
A Fistful of Paintballs - S2-E23
Revealing mistake: When Chang is getting blasted with the minigun, the safety pads under his shirt are very noticeable. (His shirt is extremely "puffed out" and you can see the outline of pads.) He's been tied up most of the episode and wasn't wearing pads earlier, so there's no way he was able to get pads on in the meantime.
Grifting 101 - S6-E9
Continuity mistake: The stacks of money the dean takes out, before getting up, changes in the next shot. One stack is completely on the black edge, then is only partly against it and closer to the other stacks. And the stack on the other end is bigger.
Advanced Safety Features - S6-E7
Continuity mistake: When Rick and Britta are talking to Todd, they're holding hands. In one shot, Rick has his hands clasped together and in the next shot, back to holding Britta's hands.
Course Listing Unavailable - S3-E18
Continuity mistake: The stars Britta puts on change during various shots. She wouldn't have had time to readjust them when off camera either, and at the end when she tried to remove them, they're stuck on pretty good.
Origins of Vampire Mythology - S3-E15
Continuity mistake: The way Britta holds the banana from the DVD cabinet changes between shots.
Geography of Global Conflict - S3-E2
Continuity mistake: When Annie starts to throw her tantrum, she knocks stuff off the table, including the microphone and small mic stand. When she's lying on the table, the mic stand is back on the table. It back on the floor when she and Jeff leave, although the Uruguay sign is now back on the table.
Geography of Global Conflict - S3-E2
Continuity mistake: When Britta is in a cage, before Chang walks in, a couple pass her and are walking out the double doors, where both doors are open. After Chang steps up to the cage and the camera shot changes, the couple is further away from the doors and walking out again, only this time one of the doors is closed.
The Psychology of Letting Go - S2-E3
Continuity mistake: The amount of the black oil stuff that covers Annie when it spills on her increases in the next shot of her, before she and Britta start fighting.
Continuity mistake: When the 7 go outside, Troy is talking to Shirley, he takes his toothpick out to say he's not an ambassador, but in the next shot the toothpick is back in his mouth.
Answer: It was part of the plot that when the boiled yam was dropped it looked like it was stepped on (which it never was). So there was no way to tell the difference between the flesh being soft because it was boiled or because it was stepped on (in the show that is, I don't know if one could tell the difference in real life). Plus, the rest of the yam wasn't boiled, so there was no evidence the yam was sitting in boiling water.
