Cured Duck is a 1945 American animated cartoon produced by Walt Disney and directed by Jack King.

The cartoon features Donald going to visit Daisy, but his temper control problems cause him to wreck the house and get kicked out.

Daisy is appalled at his behavior and shows Donald that he just needed to turn the little knob atop the frame to open it.

While trudging through the streets, Donald sees an ad in a newspaper, from the Tootsberry Institute, promising a way to cure temper issues.

The machine abuses Donald in numerous ways, from punching him, clipping the buttons off his sailor suit (a clever, in-universe explanation for why his buttons never re-appear after this cartoon: they were eliminated to increase animation pencil mileage), pummeling his feet with a brick, and even blaring loud sounds into his ear.

Just when it seems he's succeeded, the glass in the window pane falls out and smashes over his head, but even though this happens, Donald still remains in good spirits.
