Two families embark on a pleasant Sunday picnic but manage to run into a variety of issues with their temperamental automobile. Each incident requires repeated exits and reboardings by Laurel, Hardy, their wives and grouchy, gout-ridden Uncle Edgar.
Oliver is making plans to marry his sweetheart Dulcy with Stan as his best man, but the plans are thwarted when Dulcy's father sees a picture of Ollie and forbids the marriage. The couple plan to elope, and run away to a Justice of the Peace. After typical Laurel and Hardy blundering, they manage to sneak the girl away from her father's house.
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.
On the morning of his wedding to oil baron Peter Cucumber's daughter, Ollie receives a jigsaw puzzle from Stan as a wedding gift. The boys soon become absorbed in the puzzle. A taxi driver, butler, policeman and messenger boy join in as well.
