To Live and Die in Va. - S2-E17
Continuity mistake: When Rallo tells his friends the farmer's daughter joke, the friend on the right is wearing white shoes. However when Rallo says "Oh man. Murray and his friends are so lucky their mamas are dead", the right friend is now wearing black shoes. (00:10:50)
To Live and Die in Va. - S2-E17

The Essence of Cleveland - S2-E18
Continuity mistake: When Cleveland takes the tape out the camcorder, he starts writing. In the first shot, he's only just started writing, but in the next shot he is at least 70% of the way through writing. (00:12:00)
Deliberate mistake: In this episode, it is revealed Donna and Robert got together because Robert saved her from a water fountain. In "Another Bad Thanksgiving", it was shown Donna's sister introduced Robert to Donna. (00:02:20)
Continuity mistake: Cleveland goes outside in The Hurricane and gets blown all over the place. Yet reporter Dwayne Meighan is shown reporting the news outside in The Hurricane and is totally unaffected by it. (00:05:40 - 00:06:10)
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.
Continuity mistake: Cleveland has glass in his feet, but later in the episode, the glass is no longer there.
Revealing mistake: When Cleveland says "Welcome to the party over here pal!", he is putting his right hand up on the glass panel on the right of him. His right hand is not visible on the Clevelands' right side glass panel.
Continuity mistake: After Cleveland shoots the bear and the Huey Lewis like guy, the gun vanishes when he runs to Donna.
Continuity mistake: When Cleveland pulls the gun off his back, he also pulls of a piece of his skin off as well. When Cleveland and Donna kiss, the wound has vanished.
Continuity mistake: When Cleveland tells Junior to ask out Whitney, the door handles on the lockers in the background are on the left side of the locker. A few moments later, the handles are now on the right. (00:02:10)
Continuity mistake: Junior isn't able to fit through the door after returning from Choni's Cantina (the first time). Yet Junior is able to fit through the door in other episodes. (00:04:15)
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)
Continuity mistake: When Junior starts singing and Cecilia joins in making them a duet, the shot cuts to Cleveland. After this it cuts to a wide shot where we can see Cleveland doing nothing. In the next shot, he's suddenly finished drinking from a glass. (00:11:00)
Plot hole: Cleveland never tells his friends where Cecilia lives. Yet Lester is somehow able to call Immigration & Customs Enforcement and direct them to Cecilia's house. (00:14:05 - 00:15:10)
