WC Fields wears a hat with the top cut out of it in this film, just like the producer Mack Sennett was known to do. Fields does it for "hay fever," but Sennett did it because he thought sunlight was good for preventing hair loss.
In a very early example of product placement, there are signs depicting Baby Ruth and Butterfinger candy bars behind the counter.
Pharmacist Dilweg, trying to interest a prospective customer in something, points to a puppet of W.C. Fields and exclaims, "Rather amusing little beggar."
W.C. Fields and Mack Sennett argued bitterly over the title of this short. Fields had originally wanted to call it "W.C. Fields in a Drugstore".
This film is included on "W.C. Fields - Six Short Films", which is part of the Criterion Collection, spine #79.
