Donald's Nephews
Donald's Nephews (1938) is a Donald Duck animated cartoon which features Donald being visited by his three nephews, Huey, Dewey, and Louie. This cartoon is Huey, Dewey, and Louie's very first appearance in animation. The short, and the three nephews, was the idea of Al Taliaferro, the artist for the "Silly Symphonies" comic strip, which featured Donald Duck. The Walt Disney Productions Story Dept. on February 5, 1937, sent Taliaferro a memo recognizing him as the source of the idea for the planned short. Taliaferro subsequently introduced the nephews in his comic strip, which by this time had been renamed "Donald Duck", on Sunday, October 17, 1937, beating the theatrical release of "Donald's Nephews" by almost six months.
Donald Duck
However, with a few exceptions, there is seldom any harm in Donald's pranks. He almost never intends to hurt anyone, and whenever his pranks go too far, he is always very apologetic. In Truant Officer Donald, for example, when he is tricked into believing he has accidentally killed Huey, Dewey, and Louie, he shows great regret, blaming himself. His nephews appear in the form of angels, and he willingly endures a kick by one of them—that is, of course, until he realizes he has been tricked, whereupon he promptly loses his temper.
