Factual error: When Topanga and Ricky are looking at the Starry Night painting, Topanga reads from her pamphlet and says it mentions Vincent Van Gogh became religious around the time he painted it. Van Gogh grew up in a religious household, with his father being a minister of the Dutch Reformed Church, and Vincent himself actually had a desire to become a pastor. On the contrary, however, when he painted Starry Night, although he still believed in an afterlife, he was actually disillusioned with religion.
Continuity mistake: After Topanga angrily walks out of Cory's house, he gets out of his chair and says "She really left," with his arms and fingers outstretched. When the shot changes, his fingers on both hands are curled into loose fists. (00:12:40)
Graduation - S5-E24
Continuity mistake: When Jack is showing Shawn the framed caricature drawing, both his hands are holding the frame around the middle of each vertical side. When the shot changes, his left hand is suddenly holding the frame by the bottom corner. (00:06:10)
Graduation - S5-E24
Audio problem: When Mr. Feeny is reading off the names of all the graduates, you can hear reverb in his voice to indicate that he is speaking into a microphone. The problem is there is no microphone in front of him. You can see Eric holding the microphone next to him and singing into it, with no audio. If that microphone is turned off, then Feeny's voice should not be amplified. If the microphone is on, then we should also hear Eric as he is singing. (00:19:38 - 00:20:56)
Graduation - S5-E24
Factual error: In the episode Class Pre-Union, they were the class of 2000. In the episode Graduation, they were the class of 1998.
Continuity mistake: During this season when the kitchen door is open, from the living room you see a wall. In EVERY other season you see the actual kitchen.
Continuity mistake: When Rachel tackles Jack onto the couch and is straddling him, Jack's head ends up resting on the green and yellow pillow on the cushion closest to the door. After Jack says "She's sittin' on me, man," the shot changes and his head is now on the middle cushion. (00:16:06)
Other mistake: When Mr. Feeny is telling the story about Topanga and Cory in the first grade, he mentions that Shawn told him to leave them alone. However, the season 3 episode "City Slackers" established that Shawn wasn't in school with Cory and Topanga until he was around 12, and that he was in and out of 5 schools in different states before then. (00:18:40)
Continuity mistake: When Shawn is saying to Cory "No pudding, no 'Woo-hooing'," Cory is holding a cup of pudding with his arms raised to around his chest area. When the shot changes, his arms are suddenly down at his sides. (00:01:17)
Better than Average Cory - S6-E5
Character mistake: The placard next to Alexandra Nechita's painting "Peace Collector" erroneously calls the painting "Peace Collectors." Nechita herself appears in this episode, so it's odd that they got it wrong. (00:02:49)
Better than Average Cory - S6-E5
Deliberate mistake: When Rachel is choking and writes down "I'm choking to death" on the paper on the counter so Jack will help her, you can see she is just scribbling the pen across the paper and not actually writing anything. (00:06:36)
Better than Average Cory - S6-E5
Continuity mistake: When Rachel starts writing down that she is choking, she knocks a cup of water off the counter. After she spits out the hot dog she was choking on, the cup has reappeared on the counter. (00:06:38 - 00:07:00)
Continuity mistake: When Eric and Jack place the red tablecloth on their counter, it barely drapes over the end of the counter that is facing the camera and completely covers the side that is on the viewer's left. A couple of shots later, the tablecloth is draped over the same end of the counter down to the floor, and the left side is now exposed. (00:05:06)
Continuity mistake: When Cory first confronts Shawn over kissing Topanga in their dorm room, Shawn is looking through his drawer for a shirt. The shot goes to Cory for a second, then when it goes back to Shawn he's had time to find a shirt and put it on - the shot wasn't off him for nearly enough time to do that.
Revealing mistake: In the epilogue when Eric and Jack's skeletons collapse, the wire holding them up is visible.
Everybody Loves Stuart - S6-E7
Audio problem: When Eric walks into Cory's hearing to the theme of "The People's Court," we find out the sound is coming from a tape player in his briefcase. When he opens up the briefcase and pulls out the tape player to stop it, the volume remains the same. The volume should have increased once he opened the briefcase. (00:14:30)
Everybody Loves Stuart - S6-E7
Continuity mistake: Stuart comments on Shawn's shorter haircut in this episode, but it has been that short since the first day of college.
Everybody Loves Stuart - S6-E7
Continuity mistake: When Stuart is at the counter getting coffee while talking to Topanga, his hands are clasped together or one hand up other hand down between shots.
You're Married You're Dead - S6-E8
Continuity mistake: When Cory realises he left his engagement ring at the club, he raises his left hand to his shoulder level. When the shot changes to him saying "My ring," he is shown raising his left hand again. (00:11:56)
Poetic License: An Ode to Holden Caulfield - S6-E9
Continuity mistake: When Jack, Rachel and Eric are studying, Jack eats half his apple, then the three argue, and when it cuts back to Jack eating his apple, it is whole again.
