Yemen Party - S3-E5
Other mistake: Donna tells Fatima (Cleveland in disguise) that she married Cleveland when she "was 41, with two kids." However, the first season established that Cleveland and Donna did not see each other for 25 years after high school. Donna was 43 when she married Cleveland.
Suggested correction: It's established she's 41 and there's too many assumptions to say she's 43. First, all she said was "25 years later and you're still giving me gruff about Robert". Meaning it's been 25 years since she started dating Robert and Cleveland didn't like it, not that it's been 25 years since they saw each other. However, not everyone graduates high school at 18. So even if we assume it's 25 years since graduation, we don't know how old she was when she graduated.
Other mistake: After Cleveland introduces his friends to Junior's girlfriend Cecilia, Holt says to Cleveland he managed to take a picture of Cecilia without her noticing. However there are two reasons Holt couldn't have been able to take the picture with Cecilia standing in the position she was in. One, Cecilia was never standing in that particular position at any point during the conversation. And two, Cecilia was standing next to Junior the whole time. If it was the right way round, Junior should have been in the picture with Cecilia when Holt took it. (00:07:50 - 00:08:50)
There Goes El Neighborhood - S3-E9
Other mistake: Cleveland had a VIP Sky Box installed for the big game. Yet when Cleveland is actually watching the game not only is he not sitting in it, but there is no sign of it either. (00:00:45 - 00:03:35)
Dancing with the Stools - S3-E10
Other mistake: Cleveland drops his yellow top hat when he hurts his leg. But keep an eye on the hat when it's on the floor. You'll see it is in an unrealistic position. (00:01:30)
Other mistake: Terry and Aaron are seen behind Tori when Donna finds Cleveland having Frapps with Tori. But when the Frapp Attack video is played later, there's no sign of Terry or Aaron. (00:08:05 - 00:09:00)
Other mistake: In the scene when it shows how everyone got "Rallo'd", Donna is shown having been on the receiving end of the black eye binoculars trick. However, the pencil circle around her eye is is too big for the size of the binoculars' eye piece. (00:03:35)
Other mistake: When Cleveland attempts to use the toilet bar, the handle is on the front side of the tank. Cleveland then lifts up the seat and the seat is able to rest on the front of the tank easily. But there is a flusher on the front side and the seat could not have been able to rest on the tank easily if the flusher was there blocking the seat. (00:13:25)
Other mistake: The Slop Popper contest has Cleveland and Truepopperking33 crushing Slop Popper to answer questions they are asked. However, when the Courtney Love question is asked Cleveland doesn't have a Slop Popper in front of him. (00:16:40)
Suggested correction: Yes he does.
