Continuity mistake: When the Scarlet Pumpernickel is kissing Melissa Duck's hand at the inn, he is wearing his hat on his head but in the next shot he is holding the hat in his left hand. The wig stand on the table also has nothing on it, but in the next shot a wig suddenly appears.
Continuity mistake: When Yosemite Sam fires Bugs Bunny from the cannon, Bugs loses his prison cap, but when we see Bugs flying through the air in the next shot, the cap is back on his head again.
