Continuity mistake: At the end of the Matchmaker song all five girls jump on the bed. Before they jump on the bed both the youngest girls are on one side of the bed. The camera angle instantly changed from inside the room to outside the room looking in the window. The two youngest girls jump on the bed (on their older sisters) but the girl in blue comes from the other side of the bed. There was no way for her to get there with out us seeing her get there.

Trivia: At Orthodox Jewish weddings, while dancing is encouraged for the sake of bringing joy to the bride and groom, it is an established and accepted custom that the men and women dance separately so as to avoid a rather immodest atmosphere. Hence, the entire ballroom is divided in two; one section for the men, and the other where the women gather.
