Da Doggone Daddy-Daughter Dinner Dance - S1-E2
Continuity mistake: When Cleveland drops Cleveland Junior off at school, Junior gets out at the back of the car and he is taller than the car's height. In the next shot, he is standing at the front of the car without enough time to move there and he is smaller than the car's height. (00:01:40)
Continuity mistake: When Cleveland is trying to convince Donna to be with him, it is the middle of night. But as Cleveland and Donna kiss and the camera pans round, daylight can be seen outside the window. (00:19:55)
Continuity mistake: At the beginning of the episode, it is the middle of the night when it shows the first shot of The Drunken Clam. This is at the very beginning of the episode and not the first scene after the opening titles by the way. But after Cleveland says he lost the house to Loretta in his divorce, Quagmire asks him where he is going to live. Cleveland replies by asking Quagmire if he can stay at his house. When he says this, it is now the middle of the day. You can notice this from all the other open windows in all the other booths, revealing the daylight. (00:00:05)
Revealing mistake: After crashing the van into a lamp post, Terry looks into the wing mirror to spot the police. However, when he gets out of the van, you can see that the angle of the mirror would make it impossible to spot the police in relation to the van's position. (00:13:35)
Continuity mistake: When Cleveland, Tim and Terry are at the Broken Stool, in front of them are empty beer glasses and a top hat right next to the glasses. However, when it shows the shots of Cleveland and Terry, the top hat is now several inches away from the glasses. (00:12:00)
Continuity mistake: When Cleveland is doing his Mini Mall rap, there is a shot of him next to a bed and wardrobe. However, when the shot zooms out, next to him is now a mirror. (00:02:25)
Continuity mistake: When everyone is having breakfast and Donna tells everyone to make their beds, Donna is standing straight. However, in the next shot Donna is now slouching. (00:01:00)
Continuity mistake: When Cleveland asks Donna, Arianna and Kendra to be Cleveland's Angels, they are standing in front of the fireplace even though a few moments ago they were sitting down at the table on the other side of the room. (00:15:20)
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)
Continuity mistake: Nothing is on the couch (except for a cushion) when Cleveland creeps into the house. A remote suddenly appears on the couch a few seconds later. (00:09:15)
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: 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)
Audio problem: In the final scene when Cleveland says to Terry "I'm gonna get paid and you're gonna get laid", they both start cheering. But when it comes to the wide shot, Terry is still cheering but his mouth isn't moving. (00:19:55)
Continuity mistake: When Terry crashes the van into a lamp post, the wing mirror smashes. But after Cleveland has his flashback and Terry looks into the wing mirror to spot the police, the wing mirror is now intact. (00:13:05)
Answer: In the episode "A Rodent Like This" Rallo discovers that Cleveland Jr. is actually a secret agent who is tracking down Tim, who is actually criminal. Jr. reveals that in order to get close he had to eliminate the real Cleveland Jr. luckily Cleveland doesn't pay attention so it was easy. Whether or not this is canon or not depends on the writers.
