Episode Six - S4-E6
Continuity mistake: When Beverly and Carol are walking through the park, Carol begins having a conversation on her phone and Beverly begins to mimic what she is saying. Whilst this is happening, in the far background, there are two people shown walking in the opposite direction and also a man walking in the same direction as Beverly and Carol. As the shot ends the man is far past the other two walking in the opposite direction. The shot then changes and the man walking forwards and the other two people walking in the opposite direction walk past each other a second time.
Visible crew/equipment: When Ally kicks Austin out of her practice room the shadow of the boom mic can be seen on the wall.
Revealing mistake: When Mr. Goodman blows his nose, you can see a little pink from the makeup on his nose (to make him look sick).
Continuity mistake: Chris has a blue dye pack explode on him, covering the front of his clown costume and face. But then shortly after, the dye is gone from his face and clothes.
