Revealing mistake: When Bugs is applauding with the audience after Daffy has blown himself up, his tail disappears for a second.
Continuity mistake: When Daffy performs his time-step, there is a button on his waistcoat. But when he goes down on his knees, the button is missing.
Stage Manager: But Daffy, we bill according to drawing power.
Daffy Duck: Oh, yeah? That rabbit couldn't draw flies if he was covered with syrup. Okay, this performance will prove I'm a star.
