At the end of the cartoon, Daffy is pushing a street-sweeper's cart with "D.S.C." emblazoned on the side. This stands for the "Department of Street Cleaning", which was created in New York City in 1881 and renamed the Department of Sanitation in 1929. Daffy also is wearing a cartoon adaptation of that department's original medical-white uniform with white police-type helmet.

The wanted poster for Nasty Canasta, offering a $5 million reward for his dead body (not "wanted dead or alive"; just "dead"), lists his crimes as "rustler, bandit, square dance caller". This is an inside joke, as square dancing was a frequent pastime of the employees in the Warner Brothers animation department in the 1950s, most notably director Chuck Jones.
Gag names of the local businesses, which are all being held up by masked thieves, include Custard's Last Stand, Girdle Saloon (Come In & Get Tight), and Rigor O'Mortis (The Smiling Undertaker).
