Minecraft wiki entry for Curse_of_Binding, associated text: If a player applies the enchantment to a carved pumpkin and wears it, the player becomes unable to remove the carved pumpkin. If the gamerule keepInventory is set to true or the player is in Hardcore mode, it becomes impossible for the player to remove the carved pumpkin without cheating in-game or dying in Hardcore mode. This can be used to troll other players, as the pumpkin overlay on the screen makes the game difficult to play. Because pumpkins have no durability, they are the most effective item to use this curse on. However, most players would not deliberately equip a cursed pumpkin, although a dispenser can be used to forcibly equip it onto a player.
