Continuity mistake: During the "Petrified Florist" film that is being shown at the theatre, Lester Coward sits at a table in the Desert Inn and in the background there is a sign that reads: "Tom Collins Straight Whisky Gin Fizz." But when Coward stands up and recites his poem, the words "That's all Folks" have been added to the sign.
Continuity mistake: In the theatre, a baby goose and his father are watching the show and you can see the baby goose is sitting at the far end of the row. But when the other audience members turn around to try and silence the goose, he now has two empty seats beside him.
Continuity mistake: When we see the animals change seats at the start of the cartoon, you can see there is an aisle in the middle of the theatre, but when the show begins in the next shot, the aisle has disappeared.
