Donald’s Dilemma
Donald and Daisy are walking when he is hit by a flowerpot. He’s convinced he’s a famous singer, and he croons divinely, but does not recognize Daisy. He in fact does become famous. Daisy is devastated by her inability to get over him and sees a psychiatrist. He tells her she has to choose between the world having Donald, or her getting him back. She picks herself, and drops another flowerpot, which restores him.
A flowerpot turns Donald into a beautiful crooner who no longer recognises Daisy, and the short becomes a genuinely strange psychodrama told in flashback to a psychiatrist. It is one of the weirdest things in the Disney shorts library — Daisy's fantasy of destroying his career is played almost straight — and it has been rediscovered repeatedly by animation writers for exactly that reason.
