Continuity mistake: In episode 10 (Joey's Place) the Tanner family move Joey into the garage, redecorating it so the entire place is filled with Joey's furniture, but in this episode it shows the characters in and out of the garage which is completely empty and back the way it was before Joey moved in. Later in the episode Joey's stuff is out of the alcove again.
Character mistake: In the scene where Steve is changing the diaper on the toy, DJ asks if he would like to go ice skating tomorrow. When he says he can't she then says "well we can go tomorrow." (00:11:43)
Audio problem: This error occurs right after Jesse enters the house after having Bullet towed home. In the kitchen, when Joey says the line, "Jess, I've never seen your face this shade of green before", Joey's lips appear to be saying something else entirely.
Continuity mistake: In the first episode, in DJ's room when Stephanie is crawling across the curtain rod, you'll notice that there is a giant window, and a window behind Stephanie's bed. In later episodes, the giant window turns into a 3-paned bay window, and the window behind Stephanie's bed disappears.
Continuity mistake: In "One Last Kiss", Jesse goes to his high school reunion and then in the flashback, he rides his motorcycle into the gym and says to his girlfriend, 'I'm graduating tomorrow, what are they gonna do, expel me?' indicating that he graduated. But in this episode, Jesse says he's a high school drop-out and he needs to take an English class.
Continuity mistake: In Season 6 Episode 11, Vicky's mum redecorates Michelle and Stephanie's room, but here 3 episodes later the room is back to the old style and then after that episode it's redecorated again. (00:00:05 - 00:00:45)
Visible crew/equipment: In the beginning of the episode, Joey is preparing the game with Michelle and the team. When Joey asks if anyone has any questions, Aaron says he does and asks Joey if after the game he was going to buy them pizza or if he was too cheap. Right when the shot changes to Joey, you can see for a brief second at the top left hand corner that the mic is visible and a camera on the bottom left. (00:02:47)
Continuity mistake: In the last episode in season 5, the twins are babies. In the first episode of season 6 they look about 18 months old, and only 6-8 weeks have passed while DJ was in Spain.
Character mistake: Jesse says "Becky is going to let me know if we have a date tonight. One wink for yes, two winks for no." Becky winks twice, and Jesse says "Break out the champagne" meaning they have a date, but didn't he just say two winks mean no date?

Continuity mistake: As Michelle sits in her room, Minnie comes in. Minnie knocks over Michelle's blocks and Michelle says "hey, you better fix it." However in the next shot, the blocks are once again in their container, untouched.
Star Search - S3-E6
Character mistake: When Joey comes in the house at night and makes jokes about everything, he picks up a fake duck. Jesse says to Joey "Jess, you've been living in toon town..." Jesse mistakenly calls Joey, "Jess." (00:06:20)
Continuity mistake: When Jesse, Joey and Danny start telling Stephanie and DJ the story while they are laying in DJ's bed, Stephanie has 2 barrettes in her hair. Watch closely and then there's only one barrette in her hair, and then when Danny puts her to bed, there are 2 again.
Continuity mistake: D.J. Says Kimmy has 3 sisters but in other episodes she is an only child and in others she has a brother.
Continuity mistake: After Jesse jumps out of the plane, his dress shirt is covered in tomato juice but when he reaches the church, his shirt is clean.
Suggested correction: There is no mistake, when Jesse and Becky arrive to the church after bailing him out, while they're rushing inside he's cleaning his shirt.
The stain was so deep, he couldn't have got rid of it just by cleaning it. It would have needed a thorough wash in the washing machine.
Visible crew/equipment: When Jesse misses a shot, you can see a crew member throw the ball back. (00:08:35)
You Pet It, You Bought It - S8-E6
Plot hole: When Jesse and Michelle wake up in the morning, you can see that the picture Danny got was behind the couch, resting on the seat in the alcove. Later, when Danny goes into the living room and screams, Shorty is standing in the middle of the room, with his head in the picture, and the picture is facing the family. There is no way that the donkey could have put his head in that way.
Audio problem: Whenever Michelle is playing on the harmonica, her mouth movements on it and the noise we hear don't match at all.
Spellbound - S5-E17
Continuity mistake: D.J. writes "Michelle" on the chalkboard, and Michelle says "That's my name, Michelle." Then in the next scene, Michelle's name is not in the same writing, especially the first 'e'.
