Full House (1987) - 7 major mistakes

Revealing: In the episodes where Michelle is a toddler, during the opening you can see her point to the camera during the car/bridge part. Jesse tries to make it look cute by laughing and pushing her arm down.

Plot hole: In this episode, 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 season 6 in Educating Jesse, Jesse says he's a high school drop-out.

Continuity: 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.

Revealing: In almost every episode where Michelle is a toddler, you can always see her look to the right or left to most likely a person telling her what to do.

Continuity: The window in Stephanie's and D.J'S Room is different in this episode than in all the other episodes.

Continuity: On the first floor of the house, there are two staircases leading up to the second floor - from the kitchen and the living room. But on the second floor, there is only one staircase leading down. And it doesn't matter which one they use, they still end up coming upstairs in the same place.

Continuity: In later episodes, the door to the attic is located before the last set of stairs in the upstairs hallway. But in earlier episodes, there is no door; just a wall with a picture hanging.
