Continuity mistake: When Shawn is loading up his backpack with food from the catering table, a production assistant emerges from the kitchen and asks him if he's part of the interview. After Shawn says he is, the assistant walks away towards the front door. When the shot changes to the couch where the family is being interviewed, the assistant is nowhere to be seen, even though he walked right into the area of the shot. When the shot changes yet again, the assistant is back by the catering table, standing with his arms folded.
The Last Temptation of Cory - S3-E9
Deliberate mistake: When Cory calls Topanga from Missy's phone, he starts having a conversation with her as soon as he finishes dialing her number, with no time for the lines to connect.
Revealing mistake: When Cory and Shawn are holding band auditions, if you watch the guy that is shredding on guitar, you can see that although he is moving his fingers all over the fret board, his picking hand remains motionless, showing that he isn't actually playing and the sound was added in post production.
The Thrilla' in Phila' - S2-E21
Audio problem: When Joey is saying "Frankie, tag me," his mouth movement is not synchronized with the dialogue.
Continuity mistake: When Mr. Feeny says "As if you are returning for your 20th high school reunion", there is a red crown on Mr. Feeny's desk with Minkus sitting on a chair at the end. After the camera cuts to a close up of Minkus saying 'More like a pre-union", there is a cut to Mr Feeny who turns to him. Minkus is all of a sudden holding the crown on his lap, then he is seen putting the crown back onto the desk. (00:04:00)
Shallow Boy - S4-E5
Factual error: After Eric offends Corinna, she is able to write, record, mix, package and distribute an album of music within, at most, a matter of days to spite him. Accomplishing all that within such a short amount of time would be logistically impossible.
Continuity mistake: When Eric is hugging Angela, her arm is on his shoulder. In the next shot, when Jack is saying "How am I going to survive without money?" you can see, between him and Rachel, that Angela now has her arm on Eric's back. (00:16:58)
Continuity mistake: When Topanga puts the bucket in the garbage bag, she is holding the bag with her left arm and has her right arm in it. In the next shot, she is holding the bag with her right arm. (00:00:36)
She's Having My Baby Back Ribs - S7-E17
Continuity mistake: When Cory gets off the bed he leans against the dresser and his hands are behind him. When Topanga walks in the room, his hands are by his sides. (00:03:50)
The War (1) - S7-E15
Continuity mistake: When the show starts, Angela and Shawn are kissing. The shot changes to Topanga and Cory, who has popcorn on his shirt. The shot goes back to Shawn and Angela, when Cory is shown again, the popcorn is gone. Again the shot changes to Shawn and Angela, then back to Cory and the popcorn reappears.
Continuity mistake: When the spider is walking on Eric, it makes it past his fingers and has some legs on his wrist before the shot changes. In the next shot, the spider is still walking on his fingers. (00:16:17)
Revealing mistake: When Eric tells Cory and Shawn that the hot chocolates were $4, Cory looks up at the prices and says "that's the retail price." As the scene and the rest of the episode go on, if you pay close attention to the sign that has all the prices, hot chocolate is not an item.
Continuity mistake: In every other episode where Shawn's trailer is shown, next to the kitchen there was always sort of a hallway leading to bedrooms/bathrooms. When Shawn and Jack are in the trailer in this episode, there is one big wall.
And in Case I Don't See Ya - S6-E10
Continuity mistake: Rachel gets water poured on her and her pants are soaking wet. When she goes into the Student Union, Eric says "you got here incredibly fast." Her hair is still wet but her clothes are completely dry.
Continuity mistake: In the season 7 episode "I'm Gonna Be Like You, Dad" Alan and Amy's youngest son Joshua is shown to be an infant. However in this episode, which takes place roughly 4 months after the aforementioned episode, he is shown to be around 2 years old.
And Then There Was Shawn - S5-E17
Continuity mistake: When Feeny appears in the hall, he has his hands in front of him, and he is holding them. When Shawn touches him on the shoulder and Feeny falls on his knees, his hands are still in the same position, but when he is shown lying on the ground, his arms are now be his sides. Feeny was dead, so there is no way that he could've moved his arms.
Other mistake: When Cory goes into the apartment and starts to film Shawn and Jack fighting, he is sitting on the coffee table behind them. When what Cory is filming is shown, the camera is facing their sides, not their back. (00:10:47 - 00:11:11)
No Such Thing as a Sure Thing - S7-E4
Revealing mistake: The pitchfork that the Amish girl throws at Eric at the end of the episode is obviously made of rubber, as it wobbles when he catches it.
Other mistake: After Jack and Rachel tell everyone they broke up and Angela says to Shawn "Friends, okay?", the camera is noticeably out of focus and then comes into focus when Shawn says "Hate you or love you..." (00:05:10)
Continuity mistake: When Cory and Topanga are kissing and he puts his hand in her shirt, she stops him and says "what did you think was going to happen tonight?" Then she puts her hand on her lap. In the next shot, her hand is back on his shoulder.
