When Joey gets appointed D.J.'s lawyer, he puts his hands on her shoulders and she puts her right hand on his. In the next shot, her right arm hangs at her side.
At the beginning of the episode, when they are playing football, notice on 3:38 that Michelle's belt is hanging loose, but when she catches the ball (at around 42 mins) it is tucked in neatly.
When Michelle scores a touchdown, at the beginning of the episode, she throws the ball away, but when they are practicing their grunts, (at around 56 mins) it is there again.
The first time Becky is shown in this episode, when they are discussing what team the guys were in in high school, her hair is dyed blond. And when the guys are competing and she shows up to tape it, her hair is back to brunette.
When Stephanie decides she doesn't want to room with D.J. anymore, she moves to Michelle's room. When we see her there, her bed is already there, but neither Jesse nor Joey knew about it, so there is no way she could move the bed to another room by herself, even with help from D.J.
