Charles Chaplin underwent a bit of a creative block prior to making this film. In an attempt to generate some ideas for a new project, Chaplin strolled through the studio's prop building grabbing and playing with various objects. Ultimately, he stumbled upon a set of golf clubs and envisioned his character, the Tramp, playing golf. The incident sparked the creation of this film.
In this film, the golfers in the tee area of a hole, reach into a nearby wooden box, take out a handful of sand, and create a mound on the ground. They place their golf ball on this mound (called a "sand tee") in order to make their tee shot. Most modern audiences don't realize that manufactured golf tees didn't become popular until 1922, a year after this film was made. Although multiple patents for golf tees had been around for decades, the "Reddy Tee" finally took off when promoted by some famous golf professionals in 1922. The box of sand was called the "tee box", and modern golfers still call the tee area the "tee box".
Charles Chaplin as The Tramp takes an item out of his pocket to help open the visor of The Husband who is wearing a suit of armor. Most modern audiences probably don't recognize that the item is an old-fashioned can opener--an item a tramp would likely carry on his person.
