The Treaty - S4-E7
Factual error: At the UN conference, 'England' is shown as a member of the Security Council. England sits on both the UN and the Security Council as part of the 'United Kingdom' - not as a stand-alone country. UN nerds Leslie and Ben would have known this.
Character mistake: When Neal tells Rebecca about an Indian Idol and describes the idol to her, she tells him it's the Hindu Idol of Seeta, the goddess of wealth. Actually the idol is of Goddess Laxmi.
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)
Archer Vice: Southbound and Down - S5-E5
Factual error: When the bikers are chasing the bus, one of them crashes into the "Now Leaving Texarkana" sign. However, shortly before this, we see Cyril crashing into the sign reading "Austin. 105 miles." Texarkana is almost 350 miles from Austin.
Continuity mistake: When Kelly is putting the number card on Logan, you can see one on Kendall behind him, when he shouldn't have had one yet.

Continuity mistake: Kendra is dealt a Queen of clubs and a red seven of diamonds. When the four of clubs has been dealt, the other cards are now a black seven of diamonds and a Jack of hearts. (00:16:50 - 00:17:40)
Revealing mistake: Season 2, episode 4 (Duets): When Brittany lifts Artie from his chair and carries him to her bed, right before she puts him down, he is obviously lifting his feet to prevent them from bumping into the bedframe.
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.
You Wreck Me - S1-E5
Continuity mistake: In the scene at the golf course Bobby tees off as a left handed golfer, in the next scene he is now right handed. The golf glove has moved from his right and to his left and he also takes his shots as a right handed golfer.
Continuity mistake: Tenaya 7 is running on the treadmill in flat sandals with tan straps, she then has flat sandals with black straps as she fights the guards.
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.
Ring Finger - S1-E10
Other mistake: When Jackie uses the hammer to smash her Ring Finger, if you watch carefully the prop hammer actually hits her middle finger instead. (00:24:30)
Continuity mistake: Jill writes Hank a goodbye letter which she hands to a friend to deliver. In the letter which Hank reads the next day, Jill states how beautiful Africa is and how Hank must visit. She wrote this before she left and had not seen Africa yet.
'This Is America' or 'Fifty Bucks' - S1-E9
Continuity mistake: When Ray is talking to his son in the hallway outside of the detention room, his son has his arms out in front of him when the shot is from behind, but in the next shot facing him, his arms and body are in different positions.
Love Blurts - S2-E1
Continuity mistake: When Ted's talking about saying "I Love You" after sex, we see a flashback to the previous evening, him rolling over and saying it, then it cuts. He then talks about making it worse - we see the same scene again, this time not cutting afterwards, except it's not the same scene. The first time the duvet was down to his date's waist, the second time it stays up by her chest.
Revealing mistake: When Ruxin's phone conversation with Kevin is overheard by Jenny, she starts an online chat with Ruxin. She sends her message, but almost as soon as she's sent it, for a fraction of a second we see "reply from Ruxin" appear on her screen, before the shot cuts to Ruxin actually seeing it and writing his reply.
Episode #1.4 - S1-E4
Revealing mistake: Mrs. Weston's baby is obviously a doll.
