Soup's On is a 1948 Donald Duck animated short film directed by Jack Hannah, produced in Technicolor by Walt Disney Productions and released to theaters by RKO Radio Pictures.In the short, Donald cooks a turkey dinner for his nephews Huey, Dewey and Louie, but when they come to the table with dirty hands, he punishes them by sending them to bed. The nephews escalate the battle, and when Donald is knocked unconscious, they trick him into thinking that he has died and become an angel.

While Donald's relationship with his nephews Huey, Dewey and Louie had deepened significantly by 1948 in Carl Barks' Duck comics, the nephews of the cartoons are still the identical mischievous troublemakers that they were when first introduced ten years earlier. The Encyclopedia of Walt Disney's Animated Characters spotlights this short as a particularly potent example of the nephews' malicious behavior:

Sometimes... Donald is the totally innocent victim of the Nephews' practical jokes. In Soup's On, one of the truly classic contests between the Duck and the kids, his only sin is to insist that they wash their filthy hands before sitting down to eat the great turkey feast that he has cooked for them all. Their response is as cooperative as you might expect... Huey, Dewey and Louie are indistinguishable: the three of them act with a single evil mind.
