Some minute observations:
(1) The sign on the Stooges' box car says "C. M. & St. P. R. R." This seems to be a slightly mangled initialism for the
Chicago, Milwaukee, St. Paul and Pacific Railroad--the C. M. St. P. & P. R. R.
(2) In the box car, Curly unknowingly spills a container of baking powder into the batter from which he makes a second pancake. The only consequence that this set-up has is that the batter generates a big bubble, which Curly punctures with a fork. In
Husbands Beware, Shemp's excessve use of baking powder produces gigantic biscuits that are harder than wood (are there other shorts in which the same setup is used?). You would expect something more to be made of the set-up!
(3) When the Stooges try to demonstrate what they know about kissing, the girl that Curly tries to kiss says, "Oh, Mr. Howard!" There is no way that she could know that his surname is Howard. If she had any idea of his name at all, she would have to think that it was Smith, as the telegram that Moe hands to Mr. Swinehardt refers to "Mr. Frank Smith." I looked in the page on the movie and under "Stooge Goofs" I found this explanation (faulty character codes removed):
According to BeAStooge from the message board, the original script had the Stooges as staff scriptwriters for the studio. The kissing scene was shot before the film was revamped, and they forgot to change the "Mr. Howard" reference.
By the way, I seem to recall reading somewhere that Jerome Howard was actually quite a chick magnet. I suspect that this is why the two girls who are using the ball washer on the golf course in
Three Little Beers never stop smiling while Curly is talking to them.
(4) The irascible German movie director Mr. Swinehardt—surely it is he rather than Mr. Fuller Rath who seems to be the one at Carnation Pictures who is full of wrath—is played by
Harry Semels, who figures in my memory mainly as the irascible French landlord in
Wee Wee Monsieur. This is his second appearance in a Stooge short, following his first in the immediately preceding
Three Little Beers, as the second irascible (or at least irate) Italian groundskeeper ("Why you choppa choppa choppa?").
