Một đêm tại rạp diễn - A Night in the Show (1915)

Two disruptive theater patrons, the wealthy drunk Mr. Pest (played by Charlie Chaplin) and the rowdy working-class Mr. Rowdy (also played by Chaplin), attend a live vaudeville theater production. Their constant antics, seat-hopping, and physical altercations quickly overshadow the acts on stage and plunge the entire theater into absolutely hilarious chaos.
