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.
And in Case I Don't See Ya - S6-E10
Continuity mistake: When Mr. Feeny is looking over Cory and Shawn's papers, he rests Shawn's paper on the plate with his omelet. When the shot changes, he is holding the paper in his left hand and it is raised away from the plate. (00:18:35)
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.
And in Case I Don't See Ya - S6-E10
Continuity mistake: When Cory, Shawn and Feeny are at the table, Feeny's glass is almost half full. Cory later fills it up, but in the next shot the glass is half full again. In a later shot it's full and then it's somewhere in between half full and filled up.
Santa's Little Helpers - S6-E11
Continuity mistake: When Shawn and Angela are talking in the student union building, Shawn's scarf is draped around his neck in an asymmetrical fashion, with the left side shorter than the right. When they sit down on the couch, he pulls the two sides to a symmetrical length. Throughout the rest of the time Shawn remains seated on the couch, the two sides alternate between being symmetrical and asymmetrical. (00:15:20 - 00:16:47)
We'll Have A Good Time Then - S6-E13
Continuity mistake: The picture Rachel takes of Shawn, Jack and Chet is not consistent with the framed picture Jack receives. When Rachel takes the picture, Shawn's necklace is sticking out of his shirt collar slightly and positioned to the right and he has a lock of hair draped over his forehead on the left side of his face. In the framed picture, his necklace is protruding from his collar more prominently and positioned to the left, he has no lock of hair over his forehead, and his left hand can suddenly be seen on Chet's left shoulder. Additionally, the framed picture shows Chet with his head slightly tilted back and showing his teeth as he smiles, but when the picture was taken, his head was level and he only had a slight grin with no teeth showing. (00:04:49 - 00:21:10)
