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. (Obviously done deliberately for the joke.)

Continuity: In Full House episode "Bye, Bye Birdie," at preschool when Michelle gets to wear the crown, the crown goes from the crown of her head to down at her ears and back between each shot.
