The first appearance of Butch, Droopy's arch-nemesis, who replaced McWolf in Homesteader Droopy (1954).
The title comes from the daily one panel cartoon "Grin and Bear It" created by George Lichtenstein (under the pen-name George Lichty) that was first published in 1932 and is still seen in daily newspapers and on the Internet.
Michael Lah's first solo director for Droopy after Tex Avery was in charge to work with Walter Lantz at Universal.
The fountain pen Droopy holds was in common use at the time of this short. Ball point pens, which date in patent history to the late 19th century, gradually had begun entering mainstream use in the postwar years. The ball point pen, as with many modern conveniences, came out of products developed for wartime use.
