Ranma ½: The Movie 3 — One Grew Over the Kuno's Nest - 1994

In this animated short (which is also known as Team Ranma vs. The Legendary Phoenix), poetry-spouting high-school swordsman Tatewaki Kuno comes into possession of the egg of the legendary phoenix, which is said to grant its owner incredible powers. A shopkeeper sells the egg to Kuno on one condition: "Never, never, in any circumstance, put the darn thing on your head."
