"One of the greatest satisfactions in our work here at the studio is the warm relationship that exists within our cartoon family. Mickey, Pluto, Goofy and the whole gang have always been a lot of fun to work with. But like many large families, we have a problem child. You're right, it's Donald Duck."
"The Duck is the most versatile of all the Disney characters. He can carry off any role with honors—except dumb roles or gentleman parts....He is vain, cocky and boastful, loves to impose on other people and heckle them; but if the tables are turned, he flies into a rage....it is his cockiness that gets him into most of his scrapes, because it is seasoned with foolhardy recklessness....His most likable trait is determination....The Duck never compromises. Regardless of the odds against him, he comes back again and again into the fray. When attacking a problem, he may be either cocky, cautious or cunning—or all three by turns. He seldom flies into a rage at his first rebuffs; usually those defeats serve to bring out his cleverness. He dosen't stay angry for long peroids; even in his wildest rages, he can be completely and instantly mollified with a little gratification. He is easily amused and laughs especially heartily when he thinks he has caused some person or thing discomfort."

"Donald is a very outrageous fellow, with bad manners and a worse temper, and everyone is fond of him."
