When Mama Gorilla says, "Mister Anthony, I have a problem," this is a reference to John J. Anthony, who hosted the radio show "Good Will Hour" for 20 years and gave advice to married couples. His show would open with a European-accented woman saying that line in a similar fashion.
Gosh. Here's an egg w-without an address. D-D-Daffy!
Daffy Duck: Yes, sir.
Porky Pig: This egg has no address. You'll have to sit on it and hatch it out to see who it b-belongs to.
Daffy Duck: Yes, I'll have to sit on it, and... Oh, no! Oh-ho, no! Sitting on eggs is out. O-W-T out.
In the scene where Porky grabs a hold of Daffy's leg to keep him from escaping when Daffy tells him to let go his mouth doesn't move.
