In the first scene, in addition to the gag in the newspaper headline, there is a private gag below it, in the "Happy Hardaway" story:

When you see the protruding jaw of Happy Hardaway you may think "Jay Leno!", but check this out:

Was "Happy Hardaway" an alias for Ben Hardaway? Well, here is one of the stories of how the rabbit came to be known as "Bugs Bunny", as told by the granddaughter of Ben Hardaway: My grandfather was the original drawer of the bunny, who was originally going to be named, "The Happy Rabbit." Mel Blanc said, "Why don't you name him after the cartoonist, Bugs Hardaway. Call him Bugs' Bunny. And the rest was history. My grandfather got the name "Bugs" because he was a political cartoonist and would sign his name with little bugs following after it. So, from this story, it seems the creators of this cartoon gave Hardaway the rabbit's name ("Happy"), and later the rabbit got Hardaway's name ("Bugs"). Did Hardaway play the horses? Who knows...

This is the third feature for the rabbit who would go on to become Bugs Bunny. Here, however, he is not the cool smart aleck, but completely screwball: "just Daffy Duck in a rabbit suit" - with a voice and laugh that Blanc would later use for Woody Woodpecker (also created by Ben 'Bugs' Hardaway).

But he mostly resembles Max Linder in the second half of the 1917 "Max The Heartbreaker": pestering others with his wackiness, then kicking his heels and flying off into a carefree dance. And, like the Linder film, it ends with him heading off into the horizon alone on a road.

You know what this will cost you?
Thirty days...has September,
April, June, and Montana.
All the rest have cold weather - except in the summer, which isn't often!

Truer words were never spoken.
