The Stooges get jobs selling "Brighto", what they think is cleaning fluid. After ruining a cop's uniform and a new car, they discover Brighto is actually medicine. Taking their sales pitch to a hospital, they get into more trouble and must leave on the run when the head of the hospital turns out to be the owner of the car they ruined.

Trivia, insights & behind the scenes
Del Lord directed over 130 Columbia shorts; this was peak Stooge efficiency—shot in days, funny for decades.
The 'medicine show' con was already nostalgic by 1937, making the Stooges both behind and ahead of their time.
