Continuity mistake: While in the parking lot you can see Connie and Carla entirely when shot from the front. When they run away the gap they were looking through is so small only their faces would have been visible from the front. In addition the wall when shown from the front comes only up to their stomachs, but when they run way the wall is higher than they are. (00:05:40)
Continuity mistake: When doing the song with the "towel costume" in L.A. they put their microphones in their costumes. With one of them it's first sticking out quite a bit, while in the next shot only the head of the microphone sticks out. (00:18:20)
Continuity mistake: While driving to L.A. the mustard stain on Connie's face changes position and shape. (00:09:45)
