Continuity mistake: In the scene where Josh tries to prove Susan is cheating on Drake with him, after Drake comes out of the closet the camera is facing him and the right side of Josh's shirt is on his right shoulder. In the next shot, it's hanging off his shoulder. When the camera faces Drake again, the shirt is back on Josh's shoulder. In the final shot, the camera is facing Josh and the shirt is hanging off of his shoulder again and he fixes it.
Continuity mistake: In the beginning after Drake asks Josh, "what guitar do you think would look best." He opens up the cabinet and paint squirts his face. At first it only squirts his forehead, but when it switches views you can see his whole face is covered.
Visible crew/equipment: When Josh confronts his parents about his theory about Susan liking him, as the camera zooms in you can see the microphone in the upper left hand corner for a second.
Chosen answer: Well, she is the most liked sibling, so she can probably get more out of her parents, or get money from both of them without the other knowing, or as we saw in the Gary Grills episode she can get money from people easily by telling them all sorts of stuff.
