Visible crew/equipment: In the scene where Stephanie, Michelle, and Joey call the 1-800 number to report a problem with Michelle's Rigby, you can spot a microphone, for about a second, at the top of the screen right at the part where Michelle is saying, "That's us".
Continuity mistake: When DJ and Stephanie are done playing with the twins and Jesse comes in, he takes the booties off their feet, thinking that they still had their hospital bracelets on. While he is still in the kitchen, you can see that the booties are on the table between the twins. These keep changing positions in between shots, even when Jesse goes in the living room leaving the twins unattended.
Deliberate mistake: Jesse is looking for his keys and thinks Michelle took them. Near the end, Joey comes home and finds the keys in the door, hands them to Jesse, who puts them in his pocket. A few seconds later Danny comes home, takes Michelle into the kitchen. Joey and Jesse exchange a couple lines and go into the kitchen, where Michelle is sitting in a booster chair at the table. The 3 guys chat for a few minutes, then Jesse is going to leave, but can't find his keys again. It turns out Michelle has them. But how did Michelle get them? She was in the booster seat the entire time Jesse was in the kitchen and Jesse never went to that end of the room, so there's no way she could have gotten them.
Revealing mistake: I'm not sure of the episode, but it is somewhere in Season 7. The family was having dinner while Nicky and Alex were upstairs. When the Tanners were having ice cream sundaes, Jesse decides to bring some upstairs to Nicky and Alex. When he sets them on the table upstairs, you could see that they are props.
Continuity mistake: Watch Michelle's feet when she is jumping on the bed. At first she has two socks on, then when jumps off the bed, she has only her right sock on. Then, after Aaron says he should be president of their club, Michelle has both her socks. And when the club decides to pick the one who gets the Mighty Mutant Super Fortress as president, Michelle only has her right sock on.
Continuity mistake: The address of the Tanner house is 1882 Gerard Street, but in the scene where Joey brings Roxy home for a family dinner for the second time, and they are standing outside of the front door, you can see the numbers on the house are 1892 instead of 1882.
Continuity mistake: Jesse is bouncing a baby on his knee and humming the theme to Bonanza, but in another episode (the one where Jesse graduates), he states that he hates that song because his dentist used to hum it while he drilled his teeth, so when he hears it his teeth hurt. When he hums it in this episode his teeth don't seem to hurt.
Character mistake: When Jesse and Becky are in the living room with Nicky and Alex they confuse the twins when Becky tells Jesse that he can take a break and try to get Alex to use the potty because he is doing the potty dance but the kid doing the dance and the one Jesse takes upstairs is actually Nicky. This is noticeable since Alex's hair is slightly lighter that Nicky's and his cheeks aren't as chubby as Nicky's.

Revealing mistake: In the scene where Denise, Derek and Michelle are throwing the frisbee, when Derek catches the frisbee, he quickly looks up at the top of the fence and his arm is way too far up to have the frisbee get to Michelle. It is very interesting that the frisbee just happens to land on top of the fence.
