La Petite Adelaide

"In the third act the stage is set to represent a theatre, tiers of boxes and seats being built up across the wings. Just as La Petite Adelaide was doing her dancing specialty the chorus girls, occupying two of the boxes, leaned forward too far and the boxes and their occupants tumbled down upon the stage. The accident caused some excitement in the audience and two women fainted, but the stage panic was quickly stopped and the act was finished."
