First appearance of Screwball/Screwy Squirrel.
Screwball squirrel breaks the fourth wall just after he dispenses with the too cute squirrel, and continues to do so throughout the short. The cute squirrel character is probably a veiled dig at Disney's "Bambi."
Cinema audiences of the time would have recognized the William Tell Overture as the theme of the popular radio show, "The Lone Ranger."
The phone booth has a sign bearing the familia trademark of Bell Telephone, which served much of the nation's telecommunications needs at the time. Bell is now part of the SBC Telecommunications Network.
The dog has a framed picture of a fire hydrant hanging in his wall. This was one of Avery's running gags.
