A Night in the Show (1915)

Two troublemakers—Mr. Pest, a tipsy rich man, and Mr. Rowdy, a boisterous laborer (both brought to life by Charlie Chaplin)—slip into a vaudeville show. Before long, their bickering, seat-swapping, and slapstick scuffles steal the spotlight from the performers, whipping the whole audience into a frenzy of laughter and turning the evening into one gloriously ridiculous mess.
