Other mistake: When everyone is saying goodbye to Cleveland and Cleveland Junior, they are standing next to Cleveland's house. Then after they have left and Stewie says "What the hell? He's getting his own show?!", they are standing next to Peter's house. Cleveland's house however, is across the street from Peter's house and could have not been able to stand next to Peter's house if they are at Cleveland's house. (00:03:20)
Other mistake: Lester's house is directly across the street from Cleveland's. However, when the Child Services agent runs out of Lester's house with Ernie, he runs at 2 o'clock direction (which would be towards Holt's house), but instead ends up in front of Cleveland's house, which is in a 12 o'clock direction. (00:11:20)
Other mistake: Donna's friend Yvette stabs a man's hand with a knife when his hand was placed on a table. Yet no damage is made to the table. (00:11:30)
Other mistake: Cleveland shoots the living room ceiling, but the position of the hole is much further to the right from where the gun was pointed. (00:15:35)
Other mistake: When Terry is saying he doesn't like being strangled, he doesn't have a reflection in the van's wing mirror. (00:14:30)
Other mistake: When Cleveland and Cleveland Junior start singing the Black History Month song, the second hand on the clock doesn't move along with every second. (00:00:30)
Other mistake: In the casino montage, there is a shot showing us a roulette wheel that doesn't have a single number on anything. (00:04:05)
Other mistake: Cleveland spent several seconds trying to turn off the TV repeatedly pushing loads of buttons and manages to turn it off. The button he turned it off with was the same button he kept repeatedly pushing, meaning the TV should have turned off seconds ago if he was pushing that particular button. (00:09:30)
Other mistake: Kendra slaps the right side of Donna's face to stop her from freaking out. Donna then rubs the left side of the her face. (00:14:05)
You're the Best Man, Cleveland Brown - S1-E21
Other mistake: The clock on the nightstand doesn't have any hands on it when Donna is talking about women loving bad boys. (00:07:40)
Harder, Better, Faster, Browner - S2-E1
Other mistake: Donna starts drinking Tyler Perry Presents Wine. The drink level remains the same whilst drinking it. (00:07:35)
Other mistake: The block of apartments that Robert lives in is two stories tall. Yet a few seconds later Rallo says "Man, we're three stories up". How can they be three stories up if the block of apartments is only two stories tall? (00:04:05)
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.
