Continuity mistake: When Michelle goes to Taylor and Chad's apartment to take a shower, she is started by seeing their snake, and she jumps on the couch in her towel. The towel is wrapped around her body and tied at the middle of the chest, and she's also clutching it closed with both hands. Then there's a cut to Taylor exclaiming, "You're not a man." When it cuts back to Michelle, from behind, suddenly the towel is open.
Audio problem: When Romy is talking to Elena, Romy is eating chips. Before she says one of her lines she eats a handful of chips. Not only did her mouth not move, but it would be impossible to talk that way with that many chips in your mouth.
