When Jesse reminds Becky of the time the boys got into her makeup, her arms change position between shots.
When Jesse and Becky walk in on the boys hammering in the pegs, the pegs are all almost all the way through the boards. It cuts to a very brief shot of Jesse and Becky then to a wider view of the room and most of the pegs have more sticking out the top. Also, the position of the board on the viewer's right changes between shots.
When Jesse plays hide and seek with Nicky and Alex, one twin is wearing blue pants and the other green. Jesse tickles the twin with blue pants first telling him, "Go hide!". A hallway shot is shown with a twin in green pants. Cut back to the bedroom and the twin with green pants is still in the room with Jesse.
When Jesse hides the ice cream sundaes in his shirt, he is caught by Becky, and then dumps them out of his shirt, but they do not spill, revealing the ice cream to be fake.
