Ollie, attempting to aid Stan, retrieves a hot-water bottle from the bathroom but repeatedly steps on a tack strewn across the floor.

Upon Ollie's unwitting extraction, the dentist mistakenly administers nitrous oxide gas to Stan, rendering them both unconscious.

Upon regaining consciousness, Stan and Ollie exit the dental office, still under the influence of the gas, resulting in uncontrollable laughter.

This sets the stage for a chaotic sequence involving their impaired driving, leading to a series of mishaps at a bustling intersection.

Chapters of The Sons of the Desert (the international Laurel and Hardy Appreciation Society) take their names from the duo's films.
