In this episode, Curtis, Anna's dad, is seen with his right ear pierced. However, when his ear piercing was first introduced two episodes earlier in "Opening Night," it was in his left ear.
At approximately 16:22, Sam sits down next Maya. Maya snatches her gift from underneath him and complains to Anna that he "stepped" on her gift. She should have said he "sat" on her gift, not that he "stepped" on it.
